    摘要： A work enclosure for facilitating inert gas welding of aluminum tubing has two split hinged collars clamped about the tubing, one on either side of the butt joint to be welded. The circumferential surface of each collar has an outer radially extending flange and an inner shoulder forming a bearing surface adapted to receive one of the side walls of a split housing. The housing has a tubular body portion, the side walls of which have circular openings therein for receiving the collars. The hinged housing when closed has a hooded open window therein to give the workman access to the butt joint to be welded. The housing is movable rotationally on the collars. Means are provided for releasably locking the housing to the collar. To make the weld, the workman moves the housing rotationally step-by-step on the collars about the tubing.

    摘要翻译： 用于促进铝管的惰性气体焊接的工作外壳具有夹紧在管道上的两个分离的铰接套环，一个在要焊接的对接接头的两侧。 每个轴环的圆周表面具有外部径向延伸的凸缘和形成适于容纳分离壳体的侧壁中的一个的轴承表面的内肩部。 壳体具有管状主体部分，其侧壁在其中具有用于接收套环的圆形开口。 关闭时铰链外壳上有一个连帽的敞开的窗户，以使工人进入待焊接的对接接头。 外壳可以在套环上旋转移动。 提供了用于将壳体可释放地锁定到套环的装置。 为了进行焊接，工作人员将壳体旋转地沿管道的套环移动一步一步移动。
