对于一些空间特别狭小或需要远距离焊接的焊缝,标准的焊枪常常难以满足现场环境施焊的需求。通过对常规CO2气体保护焊焊枪适当改进,成功修复了高压加热器内部狭小空间断裂焊缝。 For some special small space or the need to weld long distances, the standard welding torch often difficult to meet the needs of the field environment welding. By properly improving the conventional CO2 gas shielded welding torch, the successful repair of the fractured weld in the narrow space of the high pressure heater was successfully completed.
