CWC-BookletF1 9

This document provides information on TIGFIL 70S-2 SPL filler alloy for gas tungsten arc welding of C-Mn steel. It is a triple deoxidized copper coated C-Mn steel filler alloy that meets impact requirements at -46°C. The alloy produces a strong, tough, and ductile weld metal when used for welding NACE pipes and pressure vessels made of unalloyed and micro-alloyed structural steels with specified ultimate tensile strengths up to 520 MPa. Storage and handling requires keeping the alloy dry.
