1) There are 2 pieces of extending boom and corresponding welding torch carriage in one set of this Small Cylinder Body Circumferential Welding Machine. So, workpieces can be welded at its both ends at the same time;
2) The 2 pieces of extending boom are for the purpose of feeding in and retreating welding torch, before and after welding, in this cylinder application Circumferential Welding Machine. This is for avoiding collision between welding torch and workpiece;
3) The upright workpiece supporting rack can be adjusted along the bottom rail, on platform of the Circumferential Welding Machine, accommodating varied length of cylinder body;
4) In the righthand photo, the small cylinder body was being carried out strap cladding, or built-up welding in this Circumferential Welding Machine.
1) This set of Small Pipe Flange Circumferential Welding Machine is for specifically making circumferential welding on small flanges;
2) The specialty of this Circumferential Welding Machine is, as shown in the lefthand photo, there is a set of small Welding Positioner assembled at left end of the machine body, serving as workpiece bed, for available on changing angular position of the workpiece for optimum position welding. The pipe flange in this Circumferential Welding Machine can be adjusted within the range of 0°~45°;
3) Correspondingly, welding torch in this Circumferential Welding Machine is kept at 90° upright downward all the while.
