120mm Diameter Elbow Welding Machine

This 3N-380V 50/60Hz power welding machine supports welding diameters of 80–350mm with angles of 45°–90°/15°–60°. It welds cold rolled steel (0.3–0.8mm), galvanized sheet (0.3–0.8mm), and stainless steel (0.4–0.6mm) at welding speeds of 3–9m/min, with a 6mm overlap; it uses 2mm copper wire, cooling water of 4MPa/8.5L/min, and compressed air of 0.8MPa/600L/min (≤25°C). Welding power is 50–100KVA, and the unit measures 2300×950×1600mm with a net weight of 1.0T.

Purpose and Scope of Use

This machine is specialized welding equipment for bending pipes and elbows, mainly for ship pipe bending applications. It is used for seam welding two-piece, bent pipe sections made from cold-rolled sheet, galvanized sheet, stainless steel sheet, and cold-rolled base material. The weld seam is neat, dense, and uniform, providing reliable sealing, strong weld integrity, and high production efficiency.

The device uses a copper wire as the middle electrode to help prevent electrode damage caused by the galvanized layer, thereby ensuring stable welding quality.

The equipment includes two elbow welding units: one internal seam welding machine and one external seam welding machine.
