无光焊接法是我厂冷锻车间沈友泉、顾伟毅、蒋召华等老师付学习兄弟厂经验,在本厂试验成功的一项焊接新技术。它不但可以从根本上改善焊工的作业条件,消除焊工职业病,而且也可以大大提高生产率。无光焊接的原理基本上是和电渣焊一样的。它并不象电弧焊那样利用电弧所产生的高温和热量来熔化焊件和焊条金属,而是利用电流通过熔渣而产生的电阻热来熔化金属,使焊件凝结在一起。这样,由于在熔焊过程中在焊条上面复有一层熔剂,
Matt welding method is my factory cold forging shop Shenyou Quan, Gu Weiyi, Jiang Zhaohua and other teachers pay to learn brother factory experience in the factory test a successful welding of new technologies. It can not only fundamentally improve welder’s working conditions, eliminate welder occupational diseases, but also can greatly improve productivity. Matt welding principle is basically the same as electroslag welding. Instead of using the high temperatures and heat generated by the arc to melt the weldment and electrode metal, as arc welding does, it uses the resistance heat generated by the current through the slag to melt the metal and cause the weldment to condense. In this way, due to the welding process in the electrode with a layer of flux,
