制作电焊机用量最大的是矽钢片,变电器材也都离不开它,是贵重的金属材料。如何利用边角余料生产电焊机,便成为当前最现实的课题。我们从1970年以来曾经利用生产电动机的边角料制做了一批BK—400及MT—500的交流电焊机,效果良好。利用边条矽钢片制做电焊机最关键的是如何将矽钢片紧叠在一起。由于矽钢片是用小条拼起来的,不像整片矽钢片那样用冲 Making the largest amount of welding machine is silicon steel sheet, substation equipment are also inseparable from it, is a precious metal material. How to use the edge more than expected production of welding machines, it has become the most realistic topic. We have made a series of AC welding machines of BK-400 and MT-500 from the scrap production motor production since 1970, and the effect is good. The use of edge made of silicon steel welding machine is the most critical how the silicon steel sheet together. As the silicon steel strip is put together, unlike the whole piece of silicon steel with red
