GMAW-P WELDING OF COPPER-NICKEL PIPE JOINTS FOR SHIPBUILDING APPLICATIONS

GMAW-P WELDING OF COPPER-NICKEL PIPE JOINTS FOR SHIPBUILDING APPLICATIONS

The manual gas tungsten arc welding (GTAW) process that is typically used to weld copper-nickel pipe joints for ship designs has relatively low productivity due to slow travel speeds and low deposition rates. In this paper, we demonstrate the feasibility of semi-automatic and robotic GMAW-P for all-position welding of copper-nickel pipe joints for ship designs and how this technology can yield significant productivity benefits.
