Product Overview
Solve your business pain points through innovative technical solutions
This PPEW series chuck through-hole automatic pipe welding machine is mainly used for automatic welding of pipelines and tanks across various industries. It can clamp the workpiece end via the chuck, or clamp and drive the workpiece by passing it through the center of the chuck for rotary welding. It enables automatic welding of pipe-to-pipe, pipe-to-fittings, small tanks, and more. The cantilever welding machine can travel and move to meet circumferential seam welding along the pipe axial direction, and both beveled butt circumferential welds and socket fillet welds can be welded automatically.

Welding Quality
Strict process standards ensure the reliability of every weld point
- Inspection passed: Good welding quality; weld RT/UT inspection passed;
- Mechanical properties: Meets requirements for pressure testing or mechanical property tests such as impact, tensile, and bending;
- Attractive appearance: The weld is well-formed, with no defects such as porosity, undercut, cracks, slag inclusion, lack of penetration, or lack of fusion.
