The JCJS and JSL Series Welding Manipulators are core process equipment for automated welding in boiler, pressure vessel, pipeline, and metal structure manufacturing. Designed to integrate seamlessly with turning rolls, positioners, and overturning machines, they form complete, high-efficiency automatic welding systems. These manipulators excel at internal/external longitudinal and circumferential seam welding on pressure vessel cylinders, large-diameter pipes, and spherical heads, as well as surfacing applications on inner walls, heads, and reinforced opening areas.

The JSJZF Series Lifting Type Longitudinal Seam Welding Machine is a heavy-duty, automated welding solution designed for large-diameter, extra-long cylindrical and tank workpieces. Built with a vertical lifting mechanism and high-precision welding carriage, it delivers consistent, high-quality longitudinal seam welds for pressure vessels, large storage tanks, petrochemical equipment, and heavy industrial pipelines.

The Fixed Longitudinal Seam Welding Machine is a high-precision, automated solution engineered for the longitudinal seam welding of cylindrical, conical, and plate workpieces. Integrated with advanced P+T (Plasma + TIG) Welding System Technology, this machine delivers superior one-side welding with back formation, ensuring high efficiency, consistent quality, and excellent weld aesthetics for stainless steel, carbon steel, and alloy steel materials.
