Wps 1010 Ifr

This welding procedure specification is for gas tungsten arc welding of single vee joints between 2.77mm and 11.08mm thick plates of ASTM A333 Gr6 and A350 LF2 steel. The welding will be done manually in all positions using a 2.4mm thoriated tungsten electrode and Comweld LW1-3 filler wire with argon shielding gas. The minimum preheat is 10°C, the maximum heat input is 1.48 kJ/mm, and the maximum interpass temperature is 122°C. Post-weld heat treatment is not required.
