摘要:
This back-shielded welding method: forms notches (21, 22) in the abutting edges (15, 16) of two weld metal surfaces (2,3) that are to be brought into contact so as to form, between the two weld metal surfaces (2, 3), a slit-shaped gas supply opening (17), which allows the front side and the back side of the weld metal surfaces (2,3) to communicate and which expends in the direction that the weld bead is to be formed; then forms the gas supply opening (17) using the notches (21, 22) by abutting and temporarily fixing the abutting edges (15,16) of the weld metal surfaces (2, 3) to each other; then forms the weld bead while supplying an inert gas from the gas supply opening (17); and closes the gas supply opening (17) using the weld bead.
摘要(中):
这种背面保护焊接方法:在两个焊接金属表面(2,3)的邻接边缘(15,16)中形成切口(21,22),两个焊接金属表面(2,3)将被接触以形成在两个焊接金属 表面(2,3),狭缝状气体供给开口(17),其允许焊接金属表面(2,3)的前侧和后侧连通,并且沿焊缝的方向消耗 要形成 然后通过使焊接金属表面(2,3)的邻接边缘(15,16)彼此邻接并临时固定而使用凹口(21,22)形成气体供给开口(17) 然后在从供气口(17)供应惰性气体的同时形成焊道; 并使用焊缝封闭供气口(17)。
