The longitudinal seam welding machine of the cylinder body is butted with the longitudinal seam of the flat plate.
Adapt to gas welding, submerged arc welding, argon arc welding and other welding methods.
Single-sided welding, double-sided molding, to ensure welding quality.
There is a back gas protection device to protect the workpiece from deformation and the appearance of anti-weld seams during the welding process.
The equipment is controlled by PLC and is widely used in automatic arc welding industries such as petrochemical industry, pressure vessels, hot water tanks, electric power construction, and stainless steel products.
