PPGW Series Roller-Type Automatic Pipe Welding Machine
Product Overview
Solve your business pain points through innovative technical solutions
The PPGW series roller-type automatic pipe welding machine consists of a roller-type pipe welding positioner and a mobile cantilever welding machine. It uses the roller-type pipe welding positioner to drive the workpiece to rotate 360°, and can also tilt the workpiece by ±45°, meeting the requirements for automatic welding of pipe-to-pipe, pipe-to-flange, curved pipes, T-pipes, and pipes of different diameters with offset centers of gravity. The mobile cantilever welding machine can move along the track to the weld seam positions on either side of the roller-type positioner for welding. One-time clamping enables automatic welding of weld seams at different positions along the pipe section.

Welding Quality
Strict process standards ensure the reliability of every weld point
- Inspection qualified: Good welding quality, and weld seams pass RT/UT inspection;
- Mechanical properties: Meets requirements for pressure tests or mechanical performance tests such as impact, tensile, and bending;
- Good appearance: Attractive weld bead formation, free of defects such as porosity, undercut, cracks, slag inclusion, lack of penetration, and lack of fusion.
