9/6/2016· The heat of the welding process makes the weld deposit and neighboring HAZ brittle when welding P91. Post-weld heat treatment restores toughness to the weld deposit and the HAZ. Because precision and stability in temperature control are extremely important when welding P91 pipe, induction heating is a solution that offers better control and more uniform heating of the part.
