我们用点焊方法焊接接线板时是将两只垫圈和底板点焊在一起,但是在点焊后的运输和装机时,常发生大量的脱片现象。为此我们进行了分析研究,对设备进行了一些改进。我们认为网路电压波动大是引起脱片的主要原因。因为点焊机和热处理车间的电炉由一台电力变压器供电,当电炉开得多时,网路电压就下降得多,有时甚至降到320伏以下,当电炉开得少时,网路电压就上升,有时甚至高到440伏。由于网路电压波动太大,不可避免

When we solder the terminal block by spot welding, the two washers and the base plate are spot-welded together, but a large amount of detachment often occurs during transport and installation after spot welding. To this end, we carried out analysis and research, some improvements to the equipment. We believe that the main reason for network voltage fluctuations is the cause of delamination. Because the spot welder and the furnace in the heat treatment plant are powered by a power transformer, the voltage on the network drops much when the furnace is on, sometimes dropping below 320 volts, and the network voltage increases when the furnace is low, Sometimes up to 440 volts. As the network voltage fluctuations is too large, inevitable
