PPHW Series Chuck Cantilever Integrated Welding Machine
Product Overview
Solve your business pain points through innovative technical solutions
The PPHW series chuck cantilever integrated welding machine uses a chuck to drive the workpiece to rotate 360°, and can also tilt the workpiece for welding at a 0–90° turnover angle. It meets the needs of automatic welding for pipe-to-fitting joints (flanges, elbows, tees, reducers, etc.), as well as tanks to flanges/heads. In addition to circumferential seam welding, it can perform longitudinal seam welding when necessary. It is widely used in pressure vessels, shipbuilding, offshore engineering, petrochemicals, instrumentation, pharmaceuticals, and other industries.

Equipment Features
Focus on core functions and key performance to highlight equipment advantages and application value.
- Modular design: Compact structure with a small footprint. The cantilever welding main unit and the chuck main unit adopt an integrated modular design, enabling flexible overall lifting and installation.
- Electric lifting: The chuck can be raised and lowered electrically. When welding large elbows, the chuck is raised to provide sufficient rotary clearance; when welding other fittings, the chuck height can be lowered to facilitate loading/unloading and weld observation, offering excellent operability.
- Electric tilting: The chuck can tilt electrically. The workpiece can be rotated horizontally for welding; when welding flat-weld flanges, it can also be welded at an inclined angle to achieve boat-shaped welding.
- Telescopic cantilever: In addition to basic circumferential seam welding, longitudinal seam welding can be performed when necessary using the cantilever telescopic function.
