坡口焊是用通常的焊接装置进行的,这种装置包括支承一电极(5)和一第一圆形气杯(21)以及一第二矩形气杯(25)的焊炬座,第一气杯(21)沿电极(5)引导第一保护气体流(P),而第二气杯可拆卸地与第一气杯同轴安装并围绕第一保护气体流(P)引导一更大的第二保护气体流(S)。这样产生的较宽的保护气体层流层能有效地保护深的窄坡口焊缝并且其稳定性足以完成焊缝帽。

搭接贴角焊接金属薄板的老方法,现今已基本上为对接坡口焊所取代。
The old method of soldering metal sheets together has now been largely replaced by welted joints, which are made by a special efficient mechanical device.
这种新方法需要一种专门的高效率的机械装置。对接坡口焊是一种连接迅速的施焊工艺,它可以有效地保证金属盖板的胀缩。
The welted joint, executed in this way, is a rapid means of jointing and effectively allows for expansion and contraction of the metal covering.
