工程上，为了使钢管相贯处焊缝均匀，焊接可靠，需要将钢管的焊口准确切割成型。
In engineering, in order to make the weld line even and reliable, it is needed to cut the weld opening accurately.
利用旋转电弧传感器，开展了水下湿法药芯焊丝电弧焊(FCAW)的V型坡口焊缝跟踪研究。
In this paper, we carried out a series of studies on the V-groove welding seam of the flux core arc welding (FCAW) with rotating arc sensor.
节点中的焊接宜采用完全焊透的坡口对接焊缝连接，当采用双面角焊缝连接时，可按等强设计。
And the welding connecting of them are advised to use slope butt weld that are fully welded, but when the double-sided fillet weld is used, they should be design on equal strength.
