Abstract

PURPOSE: To obtain good bonding condition without aligning MC type carbides on the welding surfaces by correcting the number of revolutions, pressure and stop timing by the specific formulae when the amount of upset after the primary and secondary pressure load rotation friction stopping of metal workingpieces is large, thereby performing welding under correct conditions.
CONSTITUTION: Working pieces of metals, particularly heat-resistant alloys containing MC carbides are subjected to relative rotation friction under low primary and high secondary pressures, after which the rotation is stopped and friction welding done. At this time, the amount of upset δR after the rotation stop associating deeply with the MC type carbide alignment is detected and when it exceeds the reference value δRO, the correction values of one or more out of formulae 1W3 [K is (δR-δRO)/δRO, N, NA are the numbers of revolutions (rpm) after the correction and at the actual friction welding respectively, P2, P1 and PA1, PA2 are the primary and secondary pressures (kg/mm2) after the correction and actual ones, respectively, ΔT is the time (sec.) from the P2 load after the correction till the rotation stop] are obtained. Then, by changing the set values, the friction welding is performed under correct conditions.
