Abstract

Provided is a vehicular door sash including a vertical pillar sash that does not cause the problem of explosion when constituting the vertical pillar sash by welding a plurality of steel plates. A vehicular door sash includes an inner member and an outer member, the inner member and the outer member being formed with overlapping portions constituting a pouch-like portion, and is characterized in that: one of the inner member and the outer member is formed with a bent portion continuous with the overlapping portions; at least a part of a plate thickness edge surface of the other of the inner member and the outer member is abutted on the bent portion; and the bent portion and the plate thickness edge surface are laser-welded at the abutted portion.

Description

technical field [0001] The present invention relates to a door sash provided with a pillar sash for a vehicle constructed by welding a plurality of steel plates. Background technique [0002] Generally, a pillar sash of a door sash for a vehicle includes a bag-shaped portion having a closed cross section on the vehicle inner side and a design portion on the vehicle outer side, and is formed by bonding a plurality of steel plates. Conventionally, the pocket-shaped portion of the pillar sash has been formed by combining overlapping portions of two steel plates by folding (Patent Document 1). In addition, welding processing (spot welding, arc welding) is known as another method of joining overlapping portions of two steel sheets. [0003] Conventionally, the steel used for the pillar sash of a vehicle door sash has generally been unplated raw steel (usually cold-rolled steel sheet (SPCC material)), however, in order to prevent the pillar sash from rusting, Attempts have been ...
