Abstract

PURPOSE: To prevent break from its generation in a welding part by changing pressing force of a base metal in two stages from low pressure to high pressure, and stopping revolution of the base metal after it has been reached to high pressure when at least one of two base metals is a superalloy.
CONSTITUTION: When friction welding is carried out using for at least one of two base metals, and alloy of creep breaking strength for 700°C, 103 hrs that is not less than 20kg/mm2, or desirably, a Ni group alloy contained MC type carbide, operation is implemented as below mentioned. The above mentioned base metals were relatively revolved in N revolutions, then, are kept for T1 hr while they are pressed with the primary pressure(low pressure) P1, after that the pressure is increased to the secondary pressure(high pressure) P2 to hold them for T3 hr, there, the revolution is stopped, after revolution stop, the secondary pressure conditions P2 is maintained for a little while, and then, the pressure is released. Further, by this method, even when the welding plane of any one of the base metal inclines in a slope of 0.3W1.2° angle, welding is available.
