Twin-Wire Submerged Arc Welding Manipulator | Longitudinal Welding of Large Cylindrical Shells

In the manufacturing of storage tanks, pressure vessels, and large steel structures, longitudinal welding of cylindrical shells often involves long weld seams, thick plates, and high efficiency requirements. To meet the needs of heavy equipment manufacturers for automated welding, Xushen provides a twin-wire submerged arc welding manipulator system designed for stable automatic welding of longitudinal seams on large cylindrical shells. With a high-rigidity mechanical structure and coordinated control system, the equipment ensures stable welding operation while improving welding efficiency and weld consistency.

The system is built around a heavy-duty welding column and boom manipulator combined with a twin-wire submerged arc welding process. It enables stable movement of the welding torch in vertical, horizontal, and longitudinal directions. The twin-wire SAW process significantly increases deposition rate while maintaining high weld quality, making it suitable for continuous welding of long seams on thick plates. The overall structure provides high rigidity and stable operation, while the welding torch is equipped with multi-directional adjustment mechanisms to adapt to different weld positions and ensure uniform weld formation.

In practical production, the twin-wire SAW manipulator is mainly used for automatic longitudinal welding of large cylindrical shells. The equipment operates reliably and is easy to control, helping improve production efficiency while reducing manual labor intensity. Xushen focuses on the development and manufacturing of welding automation equipment and can provide customized welding systems according to different workpiece sizes and welding process requirements.
