Abro steel cold welding, instructions and characteristics

How to use?

Before applying an adhesive (for example, AS 224), it is necessary to carefully prepare the work surface to be repaired, this will ensure a strong and high-quality adhesion. The damaged areas must be degreased and cleaned from chemical contamination and paint. In the event of urgent elimination of holes and sealing of gaps, preliminary measures can be dispensed with, but in such situations the quality of the connections will be lower.

This also applies to the repair of liquid-filled containers when the mixture is applied below the surface of the water. Due to the inert properties of the material, it can be used to seal aquariums, boilers, yachts and boats without preliminary preparation of damaged areas, creating a strong anchorage in the water.

Once the surface has been cleaned and sanded, a simple instruction is followed.

• The required amount of weld is cut off. This should be done perpendicularly, then you need to moisten your hands with water and mix the composition well until a homogeneous mass is obtained. The mixture will heat up a little while stirring, so you should not be intimidated.
• The mixture is applied to the base and given the desired shape. If the repair is carried out under water, then it should simply be pressed against the surface and wait until it locks in place.

Similar actions can be performed to restore threaded connections, since in cold welding composition includes fillers made of steel filings. In this case, a layer of the mixture is applied to the damaged area, and after its complete solidification, mechanical processing is carried out to obtain a cylindrical surface. Then, using special equipment, threading is performed.

Advantages

Abro Steel's versatility lies in the fact that it can be used for almost any material and under any conditions - this is its main advantage. Due to the composition, which contains epoxy resins, the preparation belongs to high-temperature and can withstand up to + 204 ° С and has a high degree of adhesion to any materials.

According to the manufacturer, it can even be used to repair the hull of sea vessels, since the welding is hermetically sealed and is not subject to destruction by sea water. Also, the tool does not react with engine oil and other liquids, so it can be safely used when repairing cars in any of its parts.

Separately, it should be said about such an important characteristic as the ability of Abro Steel to solidify during direct exposure to water. This is especially true for emergency repairs of boats and ships during sailing, as well as cars and other vehicles in rainy and snowy weather.

At least one welding tool is needed in every home, as it will help to quickly solve the problem of leaking pipes and batteries at any time. Fish lovers also note that this tool can safely patch holes in aquariums.

Most cold welding products come in a dirty gray shade, but the Abro Steel range is much broader. To save money on paint and time on additional operations, you can purchase a product in black or white, as well as shades of metal, among which steel or bronze are the most popular.

After hardening, the weld spot can be leveled with sandpaper or a file, drilled and cut, if it is necessary to repeat the relief of the surrounding surface on it.

Scope of the composition

Cold welding as a universal, neutral means allows you to reliably glue the main types of materials, both in the case of gluing homogeneous materials, and dissimilar ones to obtain a strong connection. Suitable for using the composition:

• black metal;
• non-ferrous metals;
• wood;
• wood products - OSB boards; Fiberboard, chipboard, plywood;
• ceramics;
• glass;
• plastic.

The main purpose of the train is to carry out emergency repair work:

• repair of automotive equipment;
• carrying out repair work on floating facilities;
• repair of plumbing products;
• sealing cracks and small bursts in water pipes;
• furniture repair;
• restoration work for the restoration of stone and concrete products.

When repairing automotive equipment, as for the main object of repair work using cold welding, Abro Steel can be used to seal cracks in the engine, radiators, exhaust system, seal battery housings, metal parts of the car body and body.

For the repair of floating facilities, cold welding can be used as a repair tool for the ship's hull, for sealing superstructure elements, for repairing the engine and navigation devices.

For domestic use, welding is used to repair plumbing products - sinks, toilet bowls, kitchen sinks, bathtubs, including those made of composite materials.

For emergency repair of pipeline breaks, radiators, expansion tanks, threaded connections of various types and materials, both for cold water supply systems and for hot water supply and heating.

When repairing furniture, it is used to restore surfaces, repair chips, cracks, join small cracks and splintered areas of the surfaces of wooden products and facades of chipboard materials.

For the restoration of concrete and stone products, cold welding is used as an auxiliary element to strengthen the main repair structure and as a means of filling cracks in the product surface.

Features of the use of the composition

As with most formulations of epoxy putties, Abro Steel is demanding on the preparation of the surfaces to which the compound will be applied. For better and longer-term use of the glued surfaces, it is important not only to mechanically adjust the gluing site, but also to degrease and remove paint and other chemical contaminants without fail.

At the same time, Abro Steel can be used for emergency repair of holes and breaks without additional surface preparation. However, the quality of the connection will be slightly lower, which is quite acceptable for temporary troubleshooting.

The versatility of the composition allows it to be used not only as a sealing agent for the repair of containers filled with liquid. The temperature inertness manifested during the solidification of the composition and the chemically neutral set of components make it possible to seal containers with various types of contents.

This feature makes it possible to apply cold welding of Abro Steel under the surface of the water, which is very important when repairing hulls of boats, yachts, aquariums, boilers and in other cases when it is necessary to create a strong connection in water

Specific points of application of cold welding Abro Steel

The use of steel filings as a metal filler makes it possible to use Abro Steel cold welding for the repair of particularly critical structures. Excellent qualities for the strength of the hardened surface make it possible to use it for such type of work as the restoration of a threaded connection.A layer of cold Abro Steel welding is applied to the damaged part of the thread, and after complete solidification, it is first mechanically machined to obtain a cylindrical surface, and then the thread is restored with a standard threading tool.

Manufacturers

The leading positions in the market are occupied by imported products. Domestic analogues, according to user reviews, do not demonstrate the same high quality and strength of the seam.

The most durable welding, in the opinion of professionals, as well as on the basis of expert examination data, is produced under the brands Hi-Gear, Abro, Poxipol.

• The variant from the first brand is a universal compound suitable for working on metal, as well as stone and plastic surfaces. Demonstrates heat resistance and chemical inertness.
• Abro is a two-component welding that also offers versatility. Withstands heating up to 260 ° C, suitable for use in chemically aggressive environments.
• Domestic analogues close to them in quality - "Polymet", "Almaz".

• For water supply and heating pipes, it is better to use Mastix products, but only on condition that the coolant in these systems has a temperature of no more than 120 ° C. This makes the compound an excellent choice for home welding, but does not allow it to be used for repairing production systems with a higher heating temperature.
• For heat-resistant systems, it is better to choose Kerry "Thermo" glue, which is characterized by high viscosity and the ability to withstand heating up to + 900 ° C. This compound has proven itself well when working with cast iron, steel and titanium bases, and is widely used in car repairs.
• Good quality is demonstrated by Henkel's product "Moment SuperEpoxy" for universal use, which can withstand temperatures up to 140 ° C. The composition of Adefal Trading S. A. Poxipol demonstrates similar properties, but the heating temperature during its use can reach only 120 ° C.

Types of Abro sealants

All mixtures produced under the TM Abro are of multipurpose use. Therefore, they are divided into several types, according to the component composition.

Areas of use

Cold welding applications very wide. Although safety precautions involve disconnecting the power supply before repairing the necessary parts, the characteristics of the composition allow them to glue metals that are under the influence of electrical voltage. The adhesive will work effectively on metal surfaces that are exposed to any kind of liquid, so it can be sealed against leaks in a fuel tank or radiator.

Welding is used for gluing and other materials.

• For plastic elements, excluding polyethylene. Plastic can be glued when the product is exposed to high temperature or pressure.
• For ceramics, stone, glass and wood. These materials can be glued in any order, the seam must be strong. Glue is often used for gluing ceramic tiles, to glue chips to ceramic utensils or to make crafts from ceramics, stone. Helps to reliably glue broken glass.
• For linoleum, carpet. When gluing, the floor coverings will not disperse at the seam. You can also plant linoleum or carpet on this composition before laying them, such a coating will hold for a long time, not peel off.

The properties allow the material to be used in the following areas.

• For plumbing repair. Plumbing welding is time-consuming and the glue speeds up repairs significantly. The adhesive is suitable for radiators and heating pipes made of cast iron, brass, stainless steel. The seam at the point of their connection will be no less strong than with standard welding.
• For cars. Some parts are not subject to urgent replacement, and can last a long time if they are simply glued. Often they make repairs to the muffler, glue the fuel tank, radiator or minor damage in the cylinder block.

Bonding flexible materials reduces the elasticity in the area of ​​the joint. There are no restrictions for rigid bases, almost any solid materials can be glued, not excluding concrete.

Views

If we talk about the composition of "cold welding", then it is not very complex, it contains:

• epoxy resin, which helps to impart properties of homogeneity and plasticity, which is the basis of the substance;
• a metal component that serves as a filler;
• sulfur and other components that are additives.

The composition of the weld affects the temperature level that the bonded object can withstand. You can always read these values ​​on the packages, so choosing the right option is not so difficult.

The structure of the glue can be one- and two-component

In addition, there are glue options for the material for which it is used:

• For metal objects - used both in everyday life and in professional activities, machine repair. The term of use is short, but if a significant load is not applied to the parts with welding, then this substance will reliably serve for quite a long time. It helps very well in the quick repair of plumbing, but you should not leave it there for a long time, soon replacing it with a hot welding option.
• For plastic products, it is less popular, but is used both in large industrial facilities and at home. The area of ​​application is plastic pipes and similar structures, this is a universal variety that fits any product made of the desired material.
• For gluing linoleum - the composition is capable of joining dense rubber, and therefore ideally suited for working with flooring. Using adhesives and double-sided tape gives much worse results than cold welding.

If we talk about the types of this glue, then there are several among them.

• The dotted version is actively used in the car model for working with tires. Handles stick well to aluminum pans. You can put copper on the end of the aluminum wire to make it fit better, and so on.
• Suture type - suitable for creating various body variations that must be sealed, for vessels of considerable size, as well as with sealing, which have thin walls.
• Butt option - recommended so that it is easy to connect the two ends of the wire, in addition, it can be actively used for the production of rings.
• There is also a T-type and shear welding.

Considering "cold welding" by consistency, it would be reasonable to divide it into two types:

• liquid - two-component, the process of using which boils down to the fact that the glue and hardener are mixed before use;
• plasticine (resembling plasticine), which should be kneaded well before use.

Abro specifications

To understand how the adhesive works and whether it is worth buying it, you need to understand the properties, parameters and characteristics of steel:

1. Partial hardening time - 5 minutes.
2. Full hardening time - 24 hours.
3. The voltage applied to break is 5.9 MPa.
4. Connection strength - 1050 N.
5. The stress that the seam can withstand until rupture is 258 N.
6. The voltage that the seam can constantly withstand is 2.39 MPa.

These characteristics are achieved thanks to the correctly selected components of the cold welding composition. First of all, it is an epoxy base, which itself, after hardening, has high reliability and resistance to environmental factors.

In addition to the epoxy base, it contains a metallic impurity. It is a black powder that is thoroughly mixed with a base (black cold welding). Also, before buying Abro 300 es 12ml, you need to familiarize yourself with the strengths and weaknesses of this composition.

Abro steel advantages

• The fully cured compound can withstand heavy loads.
• It is universal. It can bond plastic, rubber, metal, wood, ceramics in different combinations.
• Withstands extreme temperature changes and prolonged exposure to moisture.
• Cold welding abro steel is sold in a convenient package with detailed instructions for mixing and use.

Disadvantages of abro

• If the cold weld was not applied correctly, the strength characteristics will be significantly reduced.
• When buying on the market or in dubious places, you may get a marriage that will have problems with solidification.
• Proper storage of cold welds is essential. Otherwise, it will be unusable.

As you can see from the information above, in order to avoid possible problems, you need to follow simple rules.

Application features

The work can be divided into several stages:

1. Preparation. It is necessary to clean the work surface from debris and dust.
2. Next, you need to degrease the joints so that there are no problems with further connection.
3. Bringing the bonding area to a roughness state.
4. Mixing the components until a homogeneous mass is obtained.
5. Application to work surfaces.
6. Compression of parts for 15-20 minutes.

After 60 minutes, you can proceed to further work or use the glued object. But do not forget that it takes 24 hours to fully cure.

In conclusion, it can be said that before use, it is necessary to prepare the workplace and wear dirty clothes with gloves. Thus, you can protect the surrounding objects and skin from the sticky mass.

In everyday life, "Cold welding" is considered to be epoxy plasticine for gluing various materials, such as metal, wood, ceramics, glass, plastic, and much more ... The application of "welding" is practically limitless. For example, due to its high-temperature properties, it is widely used in emergency auto repairs, such as a leaking radiator, burnt out mufflers, a punctured battery case or even a sump. Also, it can be used in everyday life for almost any work related to furniture and plumbing. Today, we will consider the entire technological process of using "Cold welding", disassembling it to the smallest detail.

Cold welding is a method that has become famous and loved by everyone who needs to fasten metal parts. In fact, this is an adhesive composition that replaces conventional welding, but, unlike it, does not require complex equipment and certain conditions.

Such a tool can be used for gluing not only metal, but also surfaces made of other materials. But at the same time, it is imperative to read the instructions, since different types of cold welding are used for different materials and are resistant to different temperature ranges.

Application area

Cold welding Abro Steel is used in a variety of construction and restoration work:

1. When gluing various parts made of plastic, metal or wood. Thus, Abro Steel cold welding is actively used in car repair shops, carpentry workshops, in the manufacture of various models, in the repair of shoes, furniture, and metal products.
2. Application when carrying out plumbing works.The cured composition can withstand high pressure and is not afraid of prolonged exposure to moisture. Due to this, with the help of Abro Steel AS 224 it is possible to seal up leaks, additionally strengthen the joints, eliminate chips and cracks.
3. Home use. The universal composition allows bonding plastic, ceramics, metal, wood, rubber. Can repair damaged things, glue broken household appliances.

Cold welding is often used in production for gluing metal structures. The main thing is that they do not have a heavy load. In such situations, welding without the use of specialized equipment can temporarily save the day. Cold welding Abro is suitable for bonding movable steel mechanisms.

The composition of the epoxy composition Abro Steel

Steel filler, as shown by tests, helps to enhance the properties of the adhesive, forms a reliable bonding layer, and gradually through diffusion creates a strong bond.

The epoxy base, which contains high quality epoxy resin, produces an excellent homogeneous mass by stirring the stick layers in reaction with the hardener. The metal present in the composition with a fine, dusty fraction of particles contributes to high-quality mixing and the formation of a homogeneous light mass.

The formulation itself has a rather aggressive component of the hardener, since the first signs of the formation of a surface crust begin to appear within 5-7 minutes after application to the junction.

In general, it should be noted that, despite the presence of a metal filler, the composition in the solidified state is a poor conductor of electricity, chemically neutral to water, the main types of acids and alkalis.

Technical features and test results

From the moment the mixing starts, after 1-2 minutes of active mixing of the layers, a slightly viscous homogeneous mass is formed, ready for use. The soft and slightly sticky mass perfectly fills all cracks and cavities, which makes it possible to use the quality of both the outer layer of the composition as efficiently as possible, and the ability to additionally use the porosity of the surface.

The strength of the composition is achieved gradually, starting from 5-7 minutes with the formation of a dense outer crust, then by 25-30 minutes the entire composition applied to the damaged surface goes through the process of hardening with the formation of a solid mass and, finally, after 1 hour it reaches 80- 90% durability. Finally, the solidification process ends by the end of the first day. The relatively fast curing process within 1 hour allows Abro Steel cold welding to be used for emergency repairs, and the final curing results provide confidence in the strength of the joint.

The hardened layer is quite suitable for mechanical processing within 1 hour after gluing, but there are certain features regarding the strength of the hardened composition:

• glue at the junction is not designed to withstand impact deformations;
• the solidity of the solidified mass easily withstands the impact of compression, the composition shows itself somewhat worse when stretched;
• the adhesive bond is capable of providing some resistance to torsion and bending;
• the solidified mass practically does not deform during compression.

The hardening process is accelerated by keeping the bonded joint at a normal stable temperature. A gradual increase in temperature or, conversely, a decrease in temperature somewhat reduces the process of solidification of the composition.

Also, when hardening, the glue itself does not need additional additives, the composition does not require additional addition of metallized additives and to accelerate hardening, adding additional portions of the hardener.

The high-temperature regime, in which the glue is able to maintain its mechanical properties and not weaken the connection, allows it to be used in places with a heating temperature of up to 260 ° C.

A special aspect of the use of this composition is the ability of the composition to slightly increase its volume when solidifying, which is called the cork effect. This feature is great for repairing through holes and breakouts.
