Three factors that affect the welding of welding machine: welding time, current intensity, pressure.
Welding machine welding principle of resistance welding, belonging to the multi-point into the row of welding equipment, transformers require energy efficient, accurate control, in the welding time using synchronous control technology, making the welding time and sub-control welding time can be individually controlled, multiple welding circuit , To reduce the load on the welding transformer. Since the heat generated by the resistance is proportional to the square of the current passing through, the current is the most important factor in generating heat. The importance of current strength is not simply the size of the welding current, but also the current density is important. Welding pressure is an important factor in heat generation, row welding machine pressure is the use of welding stigma applied to the steel mesh of the mechanical force, through the pressure contact resistance reduction, the resistance value is uniform, to prevent local heating when welding, so that welding The effect is even. The welding time regulation of the welding machine is also an important factor in the heat generation. The heat generated by the power supply reaches the welding through the conduction release. However, the welding temperature is different due to the different welding time, and the welding result is different.
