Title:
WELDING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/146243
Kind Code:
A1
Abstract:
In this welding structure, there are a plurality of welding locations in a cross-section of a first member and a second member viewed from the axial direction of an insertion hole, and an outer peripheral line for the welding locations encompasses a curved line-shaped site and two side surface sites. The first member and the second member are welded such that, at the welding locations on both ends, the outer peripheral line of the second member and the outer side surface site at the outer peripheral line of the welding locations on both ends intersect. Defining the two intersections, where the outer peripheral line of the second member and the outer side surface site at the outer peripheral line of the welding locations on both ends intersect, to be a first intersection and a second intersection, the welding angle, which is the angle formed by two lines, a first straight line connecting the first intersection and the cross-sectional center of the second member and a second straight line connecting the second intersection and the cross-sectional center of the second member, is set to be greater than or equal to a first prescribed angle.
