锅炉联箱管体与两端法兰环焊缝,在焊接时需随着焊接的进行不断转动工件。我厂汽包车间在手工焊接联箱时,采用了一种转动联箱管身的手动回转器。手工转动器由左右两个半圆形夹箍组成,如图所示。夹箍上焊有四根φ12公匣的手柄。在焊接联箱管与法兰的环焊缝时;用螺栓将夹箍夹紧在筒身上。焊接过程中 Boiler header pipe flange with both ends of the ring weld, welding with the need to continue the rotation of the workpiece. I plant drum shop in the manual welding box, the use of a rotary joint tube manual gyroscope. The manual rotator consists of two semicircular clamps on the left and right, as shown in the figure. There are four φ12 brackets on the brackets. When welding the joint pipe and the flange girth weld, clamp the clamp to the barrel with bolts. Welding process
