通过测量双电极焊条的动态温升等试验方法研究了双电极焊条单弧焊中双电极焊条的加热和熔化。
With measuring dynamic temperature change of twin electrode, the heating and melting of twin electrode single arc welding was investigated.
同时生产加工各种电阻焊电极、埋弧焊、导电咀。
At the same time, production and processing all kinds of resistance welding electrode, submerged arc welding, conductive nozzle.
然后主要从双丝或多丝电弧焊工艺和双焊炬组合焊接工艺两个大的方面着重介绍了纵列式熔化极气体保护焊、等离子弧-熔化极气体保护焊和双电极熔化极气体保护焊等高速弧焊工艺。
Then, high-speed arc welding processes are introduced, such as tandem GMAW, PAW-GMAW and DE-GMAW, based on two categories:twin or more wires arc welding process and two-torch combined welding process.
