    Abstract: A hybrid induction welded piston including an upper piston part welded to a lower piston part is provided. The piston is produced by induction heating the upper piston part and the lower piston part, and bringing the parts together to a part growth compensated position. The method then includes rotating the upper piston part 17 to 34 degrees clockwise and then 17 to 34 degrees counterclockwise. In addition to controlling the axial position and degree of rotation, the force applied to the piston parts is controlled so that preferably no flash is formed in a narrow cooling chamber of the piston. During the rotating steps, the pressure gradually increases to a maximum level which occurs while the upper piston part is rotating in the second direction. The piston includes a homogenous metallurgical bond across the weld and no indentation on the outer surface at the weld prior to machining.

    Abstract translation: 提供了包括焊接到下活塞部分的上活塞部分的混合感应焊接活塞。 活塞通过感应加热上部活塞部分和下部活塞部分并且将这些部分一起带到部分增长补偿位置而产生。 该方法然后包括将上活塞部分17顺时针旋转到34度，然后逆时针旋转17到34度。 除了控制轴向位置和旋转角度之外，还控制施加到活塞部件上的力，使得优选地不在活塞的狭窄冷却室中形成闪光。 在旋转步骤期间，压力逐渐增加到在上部活塞部件沿第二方向旋转时发生的最大水平。 在加工之前，活塞在焊接处包括均匀的冶金结合，并且在焊接处的外表面上没有压痕。
