Abstract
A projection welding structure including plural projection portions that are provided to an end face at an open side end portion of a reinforcement member flange portion and are disposed at intervals along the length direction of the reinforcement member. The plural projection portions are each abutted and welded to welding projections formed in a surface of a panel frame. Contact between the welding member and the welded member is suppressed at locations other than at the welding projections by such a structure.
Claims6
A projection welding structure comprising:
- a first plate member with a plurality of welding projections formed on a surface of the first plate member;
- a second plate member disposed with an end face of the second plate member facing the surface of the first plate member;
- and
- a plurality of projection portions provided at locations on the end face of the second plate member facing towards the respective welding projections, projecting out from the end face and abutting and welded to the welding projections,
- wherein the plurality of welding projections soften as their temperature rises during welding so that the softened plurality of welding projections are pressed and squashed by the respective projection portions, thereby the plurality of welding projections are welded to the respective projection portions.
