我厂在制造多层包扎压力容器过程中,常在封头与筒节的环缝手工定位焊中出现严重的磁偏吹,电弧朝环缝切线方向(Y向)偏吹,并前后扰动,致使溶池不能成型,焊接工作难以进行。封头与筒节接头的坡口型式见图1。
In the process of manufacturing multi-layer bandage pressure vessel, our factory often has serious magnetic partial blow in the manual seam welding of the head and the cylinder joint. The arc blows in the direction of tangent to the girth (Y direction) As a result, the pool can not be formed and the welding work is difficult to carry out. Figure 1 shows the groove pattern of the head and tube joints.
