这句话什么意思? 关于焊接操作的要求? for wall thickness greater than 10mm and in the down hand position, the filling and capping can be performed by the spray arc metal transfer mode, with either solid or fcaw, welding shall be carried out in a protected environment(building, tent, etc.) 当壁厚超过10 mm且处于平焊位置时,填充层和盖面层可采用喷射过渡,用实心焊丝或药芯焊丝电弧焊,施焊环境必须得到保护(比如在厂房里、帐篷里等)。 熔滴过渡metal transfer---主要分成粗滴过渡globular transfer、短路过渡short circuiting transfer和喷射过渡spray transfer等形式。 so here spray arc metal transfer mode我觉得应该是“喷射过渡”。查看更多
