Cold welding Abro Steel: characteristics and applications

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.

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 drug 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 solidification, 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.

The bonding site can withstand heavy loads, but still has its limitations, so cold welding cannot fully replace the traditional one. This is, first of all, an emergency aid, which should be replaced by a full replacement of the damaged element or its full repair.

Unfortunately, cold welding cannot be as fast as conventional welding and epoxy in terms of hardening speed. 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, complete hardening occurs only after an hour, and until this moment it is better not to subject the adhered parts to loads. 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 solidified form is not intended to withstand mechanical shock.It is also not recommended to use it in places that stretch or bend, since the drug differs from silicone sealants in insufficient flexibility and ductility.

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

On them, it grasps much worse, and there is a sharp decrease in the strength of the weld. In this case, the lag of the product from the surface may not occur immediately, but after a while and very unexpectedly, which is guaranteed to create inconvenience or even endangers life. Therefore, be sure to carefully check the frozen seam and make sure it is intact.

Buyers often note that the product is easily kneaded by hands and does not require additional devices, except for a knife. But you can easily do without it.

Convenient and the very form of release of funds. The previous generation of sealants meant that you needed to carefully measure how much base fluid and how much hardener to squeeze from a tube or can. Very often, the remains of the squeezed out was wasted, as the product quickly hardened in the open air. This does not happen here, however, cold welding is also not recommended to be stored without packaging - it can dry out.

Before using cold welding AS-224 or other model, be sure to remove any dirt from the surface. If necessary, level the bonding area with a file or sandpaper so that it becomes as even as possible. Then it is necessary to degrease both surfaces with a special agent or ordinary alcohol - this will ensure the best possible adhesion.

At the very beginning of solidification, you can give the weld the desired shape, however, after that it is best to leave it until it completely solidifies. All mechanical operations are recommended to be carried out no earlier than after 1 hour - this time is enough for full adhesion of the material.

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