Resistance spot welding in Moscow The permanent connection in the process of resistance welding is formed due to the strong heating of the metal by electric current and the simultaneous plastic deformation under the pressure of the compressive force. A variation of this method is contact technology, during which the parts involved are welded at one or more points. The bond strength is determined by a number of factors: technological characteristics of electrodes (type of working surface); the strength of the applied current; the time of exposure to the electrical impulse; applied compression force; the original state of the parts. Advantages of resistance welding Resistance spot welding is characterized by an accelerated mode of operation and a limited exposure zone. Its features are high pressure in the working area, low voltage in the circuit and significant welding current. The advantages of the technology are obvious: there is practically no visible weld, the connection looks aesthetically pleasing; there is no need to purchase consumables (no additives, fluxes and electrodes are used for spot welding); the equipment operates with high productivity, processing several hundred contact points per minute; residual deformations are insignificant; welding units are convenient in operation, the process can be partially automated; auxiliary materials are air, water. The work is carried out on Italian equipment (TECNA 4647E welding machine), complete with a full set of electrodes. The overhang of the shoulders reaches 700 mm. The range of permissible thickness of welded sheets varies from 0.5 to 3 mm.
