Contact welding – the process of heating the connection with electric current with high pressure. Used in industry on stationary, modular machines and everyday life.
Consider one of the types of contact welding – home -made contact welding. It consists of a welding machine and welding contact ticks. Welding apparatus is made on the basis of a three phase transformer 380V on 36V. The transformer consists of those coils converted to 220V. Of the three coils, only one coil of 350 turns was taken – the primary. The secondary winding was made of a multi -core copper wire. Wire diameter 2 cm. Used in the welding machine before. The wire is wound on a five turns transformer. The magnetic circuit 4 by 4 cm is also used. The transformer “w” is figurative. Contact welding ticks are made of black square pipe. Two bolts and copper plate are attached to the pipe. In order to start the welding machine, the starter is used. The device is launched from the button. The wire is assigned at a distance from the heat source. To avoid short circuit, the entire device becomes on a wooden platform.
Also, one way is to use contact welding in car repair. This method is more effective than the reverse hammer method. Used to fasten various accessories in a car (bolts for mounting shelters).
Contact welding works well with stainless steel, wire and other industrial metals. Used for heating and adhesion of metals. In the jewelry industry – for the adhesion of small details.
As a result, you can easily say that contact welding is indispensable, a reliable assistant in industry and everyday life. In the repair of cars, railway lanes and aircraft construction.
