TRA-500型氩弧焊机是铝母线焊接的主要施工设备，该设备性能良好，适合连续作业，但作为焊枪的冷却水套常常由于操作工位狭窄而被电偏弧击穿。由于进口配件价格昂贵，市场上难以买到，在实践中我们选用YW-1无机胶粘剂进行大面积补漏取得了良好的效果，现把具体工艺概括如下：1 TRA-500 argon arc welding machine is the main construction equipment for aluminum busbar welding. The equipment is of good performance and suitable for continuous operation. However, the cooling water jacket as a welding gun is often electrically arc-broken due to the narrow operating position. Due to the expensive imported parts, the market is difficult to buy, in practice we use YW-1 inorganic adhesive for large-area trap has achieved good results, the specific process is summarized as follows: 1
