储能点焊,同工频脉冲点焊相比,它受网路电压波动的影响不大,对网路的冲击也很少。该点焊机的简单原理是:首先将电容器充电,储存电能,然后将储存的能量通过焊接变压器释放给焊件,使焊件局部通过大电流产生电热效应,被焊金属局部熔化,形成焊接接头。由于强大的单向脉冲电流通过焊接变压器的一次绕组,使焊接变压器的铁芯严重单向磁化,产生剩磁,影响焊接变压器的输出功率,使焊点质量不稳定。为此,应使第一个焊点与第二个焊 Energy storage spot welding, compared with the frequency pulse welding, it is not affected by the network voltage fluctuations, the impact on the network is also very small. The simple principle of the spot welder is as follows: First, the capacitor is charged to store electric energy, and then the stored energy is released to the weldment through the welding transformer so that the weldment locally generates electric heating effect through a large current, and the welded metal locally melts to form a welded joint . Due to the strong one-way pulse current through the primary winding of the welding transformer, so that the welding transformer core serious unidirectional magnetization, resulting in remanence, affecting the output power of welding transformers, the quality of the solder joint instability. To do this, make the first weld with the second weld
