Product Overview
Solve your business pain points through innovative technical solutions
The PPGW series roller-type automatic pipe welder consists of a roller-type pipe welding positioner and a mobile cantilever welder. The roller-type pipe welding positioner drives the workpiece to rotate 360° and can tilt the workpiece by ±45°, meeting the automatic welding requirements of pipe-to-pipe, pipe-to-flange, bent pipes, T-pipes, pipes of different diameters, and pipes with an offset center of gravity. The mobile cantilever welder can move along the rail to the weld seam positions on both sides of the roller-type positioner for welding, enabling automatic welding of weld seams at different positions on the pipe section with a single clamping.

Welding Quality
Stringent process standards ensure the reliability of every weld
- Inspection passed: High welding quality; weld seams pass RT/UT inspection.
- Mechanical properties: Meet the requirements of pressure tests or mechanical property tests such as impact, tensile, and bending.
- Neat appearance: Weld seams are well formed, with no pores, undercuts, cracks, slag inclusions, incomplete penetration, or lack of fusion.
