BHWM Series Pipe Inner Wall Cladding Welding Machine
Product Overview
Solve your business pain points through innovative technical solutions
The BHWM Series pipe inner wall cladding welding machine is mainly used for automatic overlay welding on the inner wall of steel pipes. It uses a liftable through-hole chuck cladding main unit to clamp the end of the workpiece to be clad. Then, the servo system drives the workpiece to rotate at a constant speed, working together with the welding torch precision displacement mechanism, oscillation mechanism, and arc-length tracking system to achieve spiral cladding on the pipe inner wall or 360° circumferential cladding. It can clad various anti-corrosion materials and wear-resistant metal materials, such as stainless steel and nickel-based alloy materials. All welding parameters are digitally processed, and automatic welding can be completed with one click according to the cladding depth.

Welding Quality
Strict process standards ensure the reliability of every weld spot
- Inspection qualified: Good welding quality; the weld passes RT inspection;
- Mechanical properties: Meets the requirements for pressure testing or mechanical property tests such as impact, tensile, and bending;
- Good appearance:Smooth transition between weld beads; the weld is well-formed and attractive, with no defects such as porosity, undercut, cracks, slag inclusion, lack of penetration, or lack of fusion.
