Flange Welding Machine

The welding of the flange and the cylinder section generally adopts the submerged arc welding method of matching the welding operator and the inclined roller frame. Inclined roller frames generally adopt 10T or 20T adjustable type (self adjustable type can be selected for small thin-walled cylinders). According to actual needs, hydraulic pressure can be used to turn the roller frame or directly fix the roller frame on a support frame with a certain angle (the angle of the fixed support can be determined according to the requirements of the welding process, commonly including 22 °, 45 °, etc.), to ensure that the welding seam is always welded in the boat welding mode. The rotation speed of the roller is controlled by frequency conversion, which ensures smooth starting and stopping. Welding allows convenient adjustment of the rotation speed of the cylinder. The welding operation frame is selected according to the diameter of the cylinder, and generally adopts a structure of high column and short cross arm.
