Abro Steel cold welding: characteristics and applications

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

Such a tool can be used for bonding not only metal, but also surfaces from other materials. But it is necessary to read the instructions, as different types of cold welding are used for different materials and are resistant to different temperature ranges.

Due to its versatility, Abro Steel stands out against many others.


Abro Steel’s versatility lies in the fact that it can be used for practically any material and under any conditions - this is its main advantage. Due to the composition, which is based on epoxy resins, the drug belongs to the high-temperature and can withstand up to + 204 ° C and has a high degree of adhesion with any materials.

According to the manufacturer, it can even be used to repair the hull of ships, as welding is sealed and 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 in car repairs in all its parts.

Separately, it is worth mentioning such an important characteristic as the ability of Abro Steel to harden during direct exposure to water. This is especially true for emergency repairs of boats and ships during navigation, as well as cars and other vehicles in rainy and snowy weather.

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

Most cold welding tools come in a dirty gray tint, but the Abro Steel line is much wider.To save money on paint and time for additional operations, you can buy a tool of black or white, as well as shades of metal, among which steel or bronze are the most popular.

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

Abro Steel takes the dye materials well, absorbing them without deforming the layer, stains, streaks, etc.


The bonding place can withstand heavy loads, but there are still limitations, so cold welding cannot fully replace the traditional one. This is, first of all, an emergency tool, to replace which it is desirable to carry out a full replacement of a damaged element or its full repair.

Unfortunately, cold welding at the rate of solidification can not be compared with such means as conventional welding and epoxy glue. For maximum effect, it is necessary to hold it for at least 5 minutes, and in situations with complex surfaces the drug dries up to 15 minutes. In this case, the complete solidification occurs only after an hour, and until this point it is better not to subject the coupled parts to stresses.This undoubtedly creates a number of difficulties when it is necessary to use a damaged device or part of it in a short time.

For all its strength, the agent in a frozen form is not intended to withstand the impact of mechanical shock. It is also not recommended to use it in places that are stretched or bent, since the preparation differs from silicone sealants by insufficient flexibility and malleability.

Another weak point of cold welding is temperature drops. Within an hour, until the medium hardens, it is highly desirable that the ambient temperature does not change, otherwise the process of hardening may be delayed.

It is often noted that Abro Steel cold welding is very sensitive to dirty surfaces.

On them, it seizes much worse, and there is a sharp decrease in the strength parameters of the weld. The lag of the product from the surface may not happen immediately, but after a while and quite unexpectedly, which is guaranteed to create inconvenience or even put life at risk. Therefore, be sure to carefully check the stiffened seam and ensure its integrity.


Buyers often note that the tool is easy to warm up with their hands and does not require additional equipment, except for a knife. But without it, you can easily do.

Convenient and the form of issue funds. The previous generation of sealants implied that you need to accurately measure out how much of the main fluid and how much hardener to squeeze out of a tube or pour it out of a can. Very often, the remains of the extruded material were wasted while the tool was quickly hardened in the open air. But this does not happen here, but it is also not recommended to store cold welding without packing - it can dry out.

Usage tips

Before using AS-224 cold welding or another model, be sure to remove dirt from the surface. If necessary, level the place of gluing with a file or sandpaper so that it becomes as smooth as possible. Then you need to degrease both surfaces with a special tool or regular alcohol - this will ensure the best possible adhesion.

At the very beginning of hardening, you can give the required shape to welding, however, after this it is best to leave it until it hardens completely. All mechanical operations are recommended not earlier than 1 hour - this time is sufficient for full adhesion of the material.

If you use the product on a surface with high humidity or an oil layer, you need to hold the drug for at least 10 minutes, smoothing it periodically. In the first minutes, press as hard as possible - this will ensure maximum adhesion to the surface material.
