2. Compact Cylinder Body Circumferential Welding Machine for Strap Cladding:

1) Structure Feature: As shown in the lefthand photo, there are 2 pieces of extending boom and corresponding welding torch carriage in one set of the compact size Small Cylinder Body Circumferential Welding Machine. So, workpieces can be welded at its both ends at the same time;
2) Welding Operation: The 2 pieces of extending boom are for the purpose of feeding in and retreating welding torch, before and after welding in the cylinder application Circumferential Welding Machine. This is for the purpose of avoiding collision between welding torch and workpiece;
3) Accommodating Varied Length of Pipe: In this Pipe Circumferential Welding Machine, the upright workpiece supporting rack can be adjusted along the bottom rail, on platform of the Pipe Welding Machine, catering on varied length of cylinder body;
4) Welding Mode: In the lefthand photo, the small cylinder body was being carried out strap cladding, or built-up welding in this Circumferential Welding Machine.

3. Small Pipe Flange Circumferential Welding Machine:

1) Usage: This set of Small Pipe Flange Circumferential Welding Machine is specifically designed, for fulfilling circumferential welding on small flanges;

2) Structure Specialty of this Circumferential Welding Machine:

a) As shown in the righthand photo, there is a set of small Welding Positioner being assembled at left end of the welding equipment body, serving as workpiece roller bed;
b) In this way, adjusting on angular position of workpiece, so as to acquiring on optimum position welding, can be fulfilled in the Pipe Welding Machine;
c) Tilting Angle: The pipe flange in this Circumferential Welding Machine can be adjusted within the range of 0°~45°;
3) Welding Position: Correspondingly, welding torch in this Circumferential Welding Machine is kept at 90° upright downward all the while.
