METHOD FOR MITIGATING RESIDUAL STRESSES IN WELDED METAL COMPONENTS USING HIGH TORCH TRAVEL SPEEDS

A process for providing a significant improvement in the detrimental tensile residual stress condition on the root side of welds, especially on the insid e wall of piping welds. The method uses a high welding torch travel speed (10 inches/min), especially on the last one or two cap passes. The proce...
