In the process of repairs or other household needs, sometimes it is not possible to use conventional welding for some reason. A good alternative can be “cold welding”, which is not completely, but temporarily can replace the first option. In order to use and choose it correctly, it is important to know what it is, and what is the principle of operation.

Features of the

Cold welding glue is a substance that can help join two metal parts without a thermal reaction. The composition can be deformed so that it is possible to reliably cover the parts by gluing them. It is most often used in the process of repairing plumbing equipment and shows excellent results when working with machines. The big advantage of such glue is the ability to glue elements that were not prepared in advance for this procedure, which speeds up the process and makes it more convenient.

"Cold welding" is the mixing of a substance with polymers and obtaining the final result. The strength characteristics of the substance will also depend on how high-quality ingredients are in the composition, as well as on the correctness of its manufacture. If, during the repair process, conditions close to ideal are created, then the glue can become stronger than the metal itself, but in reality this is almost never done, therefore the use of glue can be useful for temporary needs and a short-term way out of a problem situation.

Using "cold welding", you can work with metals such as copper, lead, aluminum, nickel, iron, cadmium and silver.

It is especially convenient to use this composition where elevated temperatures cannot be used, and the parts must be reliably soldered. Convenience lies in the fact that during the soldering process it is not necessary to work with homogeneous metals, you can connect several options that will be well attached to each other with glue.

If we talk about a number of advantages, then they should include:

  • no deformation of the metal surface due to the absence of temperature effects;
  • the seam is neat and quite strong;
  • for a number of metals, only the use of "cold welding" is possible, these include aluminum and copper, which are not connected by other options;
  • after work, there is no metal waste;

  • no need to use electricity;
  • environmental friendliness of the procedure;
  • you do not need to be trained for the procedure;
  • no specialized equipment is required.

The use of such glue can save in some situations, and in some cases it is the only possible way to connect two metal parts. It is the knowledge of the properties of this glue that will help to use it correctly.

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.It is important to correctly apply the product to the surface, exactly following the instructions, which will give a good result: a beautiful, even seam and reliably welded parts, even if the work is done on pipes with hot water.

The structure of the glue can be one- and two-component. It is important to use the first type as soon as possible, otherwise the adhesives will lose their properties. The second option can be stored for quite a long time and used as needed.

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 adhere 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.

Having the necessary knowledge, it is possible to easily choose the desired glue option in the store for its intended use, which will make the process of minor repairs convenient, and in some cases "cold welding" will be a real assistant for a long time, firmly gluing the parts.

Temperature characteristics

"Cold welding" is a compound that has good resistance to high temperatures, which makes it possible to use it for various surfaces. The standard mark that is indicated on the packages of glue is 260 degrees Celsius or some similar indicator, but this is far from the limit. It should be said separately that those compositions where the temperature indicator is indicated precisely within these limits should not be operated at such indicators for a long time. A normal environment with temporary and irregular rises in temperature will give a normal effect, but other conditions will not allow the welding to last long, and soon it will be necessary to carry out repairs again.

If there is a need to find a substance that fixes places with high temperatures, then the maximum should be 1326 degrees. This type is called high temperature welding, which is often used where it is difficult to reach with conventional welding, or it will be ineffective.

Application area

The use of "cold welding" becomes possible for products made of aluminum, cast iron, copper and other options. They actively use it in the process of eliminating the problems of plumbing equipment and heating pipes. It is not always convenient for batteries to use a hot welding option, and a properly selected adhesive, applied in the correct way, can completely replace it. In addition, the composition successfully copes with the repair of metal containers and radiators for cars, therefore, in this case, its application is especially welcome.

For polypropylene and plastic pipes, this glue is considered the best helper., because the option using a welding machine will not be possible. In addition, building supplies, garden tools, stainless steel products, all this can be corrected or corrected with the help of the right composition. Equally important is the use of glue for working with copper wires, on which it is not easy to weld aluminum lugs, but in the presence of a welding compound, the process is easy.

A special type of welding glue makes it possible to glue parts made of rubber, ceramics, wood and more, for which you need an appropriate glue that can hold parts of the products. Having decided on the material and its application, you need to choose the right glue.

If the work is carried out with automotive parts: a radiator, a gas tank, a muffler, then a composition with a metal filling is used. For those options when the operation is carried out under the influence of temperatures, and these are some parts, as well as machine components, it is important to choose a heat-resistant variety. Choosing the right variety, you should understand that the use of "cold welding" for those parts that are operated under pressure is impossible, this composition will not withstand and will burst. The exception is heat-resistant varieties, which are several times stronger, which means they sit more firmly in place.

The field of application is quite wide: from simple household needs, gluing and welding of small problem areas to use in the automotive business.

User's manual

In order to glue any parts with your own hands using welding glue, you need to do a number of preparatory steps. To ensure the best result, it is worth preparing the surface by first cleaning and treating with alcohol. When everything is ready, you need to remove a piece of welding, knead it and apply it to the place of the weld. If the glue has become soft and pliable, has acquired a brown tint, then it is completely ready for use.

After application, you need to fix the composition with a clamp, you need to wrap it with a tourniquet. For partial solidification, you need to wait about an hour, after this time it is possible to drill holes, if necessary, to cut the threads and carry out any other actions. It dries until the glue completely hardens for at least a day. If the work needs to be done on a pipe that is leaking and it is impossible to close the water, the composition is applied to the problem area and pressed tightly until it begins to harden, after which it is rewound with a tourniquet for at least an hour so as not to prevent delamination of the welding.

In the process of repairing any object using "cold welding", you should not take into account humidity indicators, they do not radically affect anything, but the air temperature should be above five degrees, otherwise you should not expect a good result. All work with glue should be carried out in a spacious room, or the room where the soldering is carried out should be well ventilated. The components themselves are harmless, but when combined with each other, they not only reliably weld surfaces, but can also affect the integrity of the human mucous membranes.

It is not too difficult to carry out any actions with welding glue., but it is important to follow the instructions clearly, therefore, mix the components of the glue in a specialized container and stir until the composition is homogeneous and plastic. "Dry welding" hardens rather quickly, because the time for using the ready-made solution is rather short, it can be from 10 minutes to an hour, after which the contents harden and are no longer suitable for use.

When applying glue to the surface to be welded, it is important to ensure that no excess material remains on the product, they should be removed after the parts have been connected. Each brand and type of "dry welding" works differently, which is why the curing time is different. In some cases, only five minutes is enough for the composition to set, and for some options it will take an hour. To completely weld the problem area and be able to use the object, you need to wait for the maximum drying time of the glue. The fastest will be ready in two hours, and the slowest will dry in 24 hours.

Work can be carried out using "dry welding" on a wide variety of surfaces, but it is important to choose the right type of glue, read the instructions for it in order to know about the curing time and not be late with the application, and also not to get ahead of the moment when the object is fully ready in order to be able to fully use it. In addition, it will not be superfluous to choose a product of a quality and trusted manufacturer that uses the necessary ingredients, thanks to which the best result is achieved.

Manufacturers and reviews

There are quite a few manufacturers of any product now, and it differs radically. There are options for domestic firms, and there are foreign options. A qualified employee can choose which of the options presented is better, therefore it is worth contacting him in the process of selecting the right composition. It is not always that a foreign brand or the high cost of a product speaks of its quality.

When choosing a welding, you need to read its composition and operating conditions. If they do not raise questions, then the glue is suitable for use. It is also worth paying attention to the date of manufacture of the sample, because after its expiration, the basic qualities may be violated.

Tips & Tricks

The process of repairing any equipment is not an easy task, and it is important to know what exactly you need to use in order not to spoil it. "Cold welding" is most often used to repair plumbing, cars and other appliances. If we are talking about cars, then it is most convenient to use such a glue for the gas tank, it helps to seal holes and problem areas without forcing the driver to purchase a new part.

In order for the work to proceed quickly and efficiently, it is best to ensure the convenience of its implementation. To close the hole, the easiest way is to adjust it with a screwdriver and screw in a bolt that will fit. "Cold welding" all this is fixed and held very securely.

If you have to deal with a radiator, then it is blown through with a compressor using water and places with damage are determined. In this case, sealing by "cold welding" is a temporary solution to the problem, and it is imperative to take more serious steps. If there is a problem in the muffler, then glue can be used only if it passes according to the temperature indicator. It is best to initially acquire a composition that can withstand maximum temperatures.

The repair process is carried out by surface cleaning and degreasing., which helps the device to serve for quite a long time. Depending on the magnitude of the problem, welding either completely removes the problem or provides a temporary solution. In cases with serious damage, an inverter or semi-automatic welding machine is used.

With the help of "cold welding" you can carry out repair work with metal objects, but you need to be sure that the product will not be subjected to strong pressure and stress, otherwise the repair will not last long. If during the operation of some parts there are vibrations that can tear parts apart from each other, then the use of glue is impractical, since in this case it is practically powerless, it is best to use hot welding and securely fix all moving parts.

The use of "cold welding" is very popular due to its versatility and ease of use. Due to its properties, the glue is convenient to apply to any surface, and the strength of the result does not raise any questions. Due to the availability of this composition, anyone who needs a quick solution to a problem with a household or with a car can purchase it, but it is worth remembering that the possibility of welding is not unlimited, and in some cases it is worth replacing it with a traditional option.
