Title:
METHOD FOR PRODUCING LIQUID-COOLING JACKET
Document Type and Number:
WIPO Patent Application WO/2020/059198
Kind Code:
A1
Abstract:
This welding step is characterized in that after only a stirring pin (F2) of a rotating tool (F) that rotates is inserted at a start position set further towards the inside than the set movement route, the stirring pin (F2) is gradually inserted to a predetermined depth while moving the central axis of rotation of the rotating tool (F) to a position that overlaps with the set movement route, and friction stir welding is carried out in a state in which γ=α-β, where the angle of inclination of the central axis of rotation of the rotating tool (F) with respect to the plumb-bob vertical plane is defined as γ, the angle of inclination of the step-side surface (12b) with respect to the plumb-bob vertical plane is defined as β, and the angle of inclination of the outer peripheral surface of the stirring pin (F2) with respect to the central axis of rotation is defined as α.
