Product Overview
Solve your business pain points through innovative technical solutions
This PPCW-series large-diameter chuck-type automatic welding machine is mainly used for automatic welding of large-diameter pipelines and pressure vessels in various industries. It uses a large-diameter chuck main unit to clamp the end of the workpiece for driven rotation, while the cantilever welding unit travels to each seam position for welding. One-time clamping enables automatic welding of weld seams at different positions on the shell, realizing fillet welds of shell + flange, and groove circumferential welds such as shell + head and shell extension joints. In addition, after adding components such as a precision heavy-duty rail track and a fore-and-aft axis oscillation mechanism to the cantilever welding unit, longitudinal seam welding of the workpiece can be achieved through the travel of the cantilever welding unit.

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