氩弧焊喷嘴(图1)结构比较简单,可是由于产量较大(年产6000个),使用一般 C620普通车床,每个人每班仅能完成20件,因此成了生产的关键。青年工人王泰花同志,虽然进厂不到两年,但她为革命刻苦钻研技术,在孙师傅等老师傅的帮助下,改进了加工氩弧焊喷嘴的旧工艺,革新成功了三位回转式刀 TIG welding nozzle (Figure 1) the structure is relatively simple, but because of large output (with an annual output of 6000), the use of ordinary C620 ordinary lathe, each class can only finish 20, so it has become the key to production. Young worker Wang Taihua, although less than two years into the factory, but she assiduously study the technology for the revolution, with the help of Master Sun and other masters to improve the processing of argon arc welding nozzle of the old process, the successful reform of the three rotary knife
