为了满足生产上的需要,我们参考有关资料,将氩弧焊枪的结构作了如图的改进,效果较好。 原来是在锥体上开缺口,依靠锥面的挤压夹紧钨丝,现改用弹簧夹头装夹钨丝,不仅牢固,而且避免了通电后的粘连现象。同时,为了改善气流的挺直性,克服其急促、紊乱状况,还增加了气室的分气孔。而且,为了增强焊缝熔池的保护,减少金属在熔化结晶过程中受空间气体的侵入,在喷嘴里装上一个衬套,并在衬套端面垫上两层80～100目的铜丝网。实践证明,这样做,焊缝
In order to meet the needs of production, we refer to the relevant information, the structure of the TIG welding torch made as shown in the figure, the effect is better. The original is open in the cone gap, relying on the cone of the squeeze clamping tungsten, is now used to clamp the collet chuck, not only strong, but also to avoid the phenomenon of adhesion after power. At the same time, in order to improve the flow of straightforward to overcome its rapid, turbulent conditions, but also increased the gas compartment air holes. Moreover, in order to enhance the weld pool protection, to reduce the metal in the melt crystallization process by the invasion of space gas, the nozzle is equipped with a bushing, and the bushing end of the pad on two layers of 80 ~ 100 mesh copper mesh. Practice has proved that doing so, weld
