Title:
WELDING METHOD AND WELDED JOINT
Document Type and Number:
WIPO Patent Application WO/2018/168896
Kind Code:
A1
Abstract:
This welding method according to the present invention comprises a step of forming first and second welded layers between a rear supporting plate, and a first member and a second member. The first member has a first surface, and the second member has a second surface. The first and second members are disposed so that the first surface and the second surface face the rear supporting plate. The first welded layer intersects the first surface of the first member at an intersection point P1, and intersects the second surface of the second member at an intersection point P2. When a straight line L passing through the intersection point P1 and the intersection point P2 is drawn, a tip of the second welded layer exceeds the straight line L. The second welded layer intersects the straight line L at an intersection point Q1 and an intersection point Q2, wherein the intersection point Q1 is inside the first welded layer or coincident with the intersection point P1, and the intersection point Q2 is inside the first welded layer or coincident with the intersection point P2.
