介绍了能满足生产要求的由机械系统、点焊系统以及控制系统组成的不锈钢复合钢带自动多点焊机。指出了薄件多点焊用的电源最好采用具有多个二次绕组输出的壳形点焊变压器;若采用旧的三相变压器,则采用V形接法,且二次绕组输出空载电压应足够高,这样才能弥补变压器漏抗过大的弊端。 The automatic stainless steel clad strip multi-spot welding machine which is composed of mechanical system, spot welding system and control system is introduced to meet the production requirements. It is pointed out that it is better to adopt the shell-shape spot welding transformers with multiple secondary windings for the power supply of multi-spot welding. If the old three-phase transformers are used, V-connection method is adopted and the output voltage of the secondary windings Should be high enough, so as to make up for the shortcomings of excessive transformer leakage.
