There are two types of friction welding machine, one is brake type and another is inertia type. Main difference between them may be the deceleration condition of rotation. Rotation is stopped abruptly in the brake type welding process, however, it is stopped gradually in the inertia type welding process. In this study, effect of the decelerating condition of rotation on the burn-off behaviour and macrostructure of joint was studied by controlling the brake ability of rebuilt brake type welding equipment in order to clarify the characteristics of each type machine. Used material was heat resisting steel FV 607. In addition, combined effect both of the axial pressure change and of the time-lag between pressure change and start of deceleration on them were also examined. Obtained results are as follows; 1) Burn-off rate increases with the deceleration of rotation. And additional burn-off during deceleration is in proportion to deceleration time. 2) When axial pressure is not changed, shape of heat affected zone becomes narrower and concave shape with increase both of axial pressure and of deceleration time. 3) When axial pressure is changed and deceleration time is sufficiently long, effect of prior axial pressure, friction time and time-lag on the shape of HAZ becomes insignificant. 4) Added burn-off at final stage by deceleration of rotation shows different effect on the shape of HAZ from that by upset pressure.
