Abstract
It is shown that maximum longitudinal tensile stresses induced in bead on nickel alloy plate welding amount to yield stress of the base metal. In the case of welding with preheating to 900 oC residual stresses decrease by 30 %
Keywords: high-strength nickel alloys, residual stresses, net method, yield stress, preheating
