Four torch pipe flange circumferential seam automatic welding machine

Product Introduction: 

The four torch pipe flange circumferential seam automatic welding machine is mainly suitable for welding the circular weld of flange and cylinder. This equipment is equipped with 4 torches on the basis of ordinary flange girth welding machine, can automatically or asynchronously perform girth welding, which can greatly improve welding efficiency and save costs. Adapt to gas welding, submerged arc welding, argon arc welding, and other welding methods.

Application scope and welding method of Four torch pipe flange circumferential seam automatic welding machine:

The cylinder circumferential seam is automatically welded. The materials are carbon steel, stainless steel, and aluminum.

Workpiece length: ≤ 6000mm diameter: Ф250mm ~ Ф650mm.

Welding method: Fusion arc welding, 4 torch welding at the same time.

Workpiece state before welding: 

Use manual spot-fixing to minimize the size of the welding spot. The operator hoisted the spot-welded workpiece to the ring seam fixture and clamped it. Before welding, the spot welding of the workpiece is firm and clean. Move the welding torch to the position of the welding seam, fine-tune the position of the welding torch, set the welding parameters (such as welding speed, arcing time, arcing time, and other process parameters) and start welding until the welding is completed. Welding method with welding gun fixed and workpiece rotating at welding speed. The rotation of the workpiece adopts frequency conversion stepless speed regulation. The welding torch can be oscillated and non-oscillated during welding. Automatic arc extinguishing after welding one circle or preset welding length.
