苏联某研究所研制了一种用于对复杂结构工件进行不熔化极气体保护电弧焊的焊枪(参见附图),借助于这种焊枪可以焊接厚度很小的金属(～0.05毫米)。该焊枪既可用于手工焊,亦可用于自动焊。它无需增加喷口中电极的伸出或更换上长
A research institute in the Soviet Union developed a welding torch (see the attached drawings) for inflatable gas-tight arc welding of complex structural workpieces with which a very small thickness of metal (-0.05 mm) can be welded. The torch can be used both for hand welding, can also be used for automatic welding. It does not need to increase the nozzle out of the electrode or replace the length
