Welding Equipment with Five Wires for Longitudinal Seam Welding of Steel Pipes

Longitudinal Seam Welder for Steel Pipes
Diameter of the steel pipe capable of being welded: 406mm-1422mm
Length of the steel pipe capable of being welded: 6m-12.2m
Wall thickness of the steel pipe capable of being welded: 6mm-40mm
Materials of the steel pipe capable of being welded: X42-X80
One-set tack welding: Tack welding can be successively conducted by gas shielded arc welding with thick wires in high speed after the steel pipe is formed, and the travel speed is 3-6m/min.
Two-set (or three-set) welding inside the pipe with four wires: the submerged arc welding with four wires is conducted inside the steel pipe after the tack welding.
Two-set (or three-set) welding outside the pipe with four or five wires: the submerged arc welding with four or five wires is conducted outside the steel pipe after welding inside the pipe.
