High deposit TWIN TIGer double torch solutions are available for the internal cladding of pipes with an inner diameter of minimum 5” and standard lengths of 18m
Family: Turnkey solutions for cladding of tubes and pipes
Horizontal weld overlay / cladding
Internal CRA cladding can successfully be carried out by overlay welding. The horizontally positioned pipes are rotated around their longitudinal axis while the torches with the attached wire feeding devices are mounted at the end of a welding lance and guided along the inner wall. A bi-cathode TIG/GTAW cladding process named TIGer, exclusively developed by Polysoude, executes a smooth surface of the corrosion-resistant layer, which together with low dilution rates between deposit and substrate, produces reliable results and significantly improves productivity.
Pipe End Cladding Rig
Two synchronised PC 600-3 HW power sources control the longitudinal movement of the lance, the pipe rotation and supply the TIGer torch
