LASER-WELDED JOINTS AND METHODS FOR PRODUCING THEM

Abstract

A laser welded joint having excellent compressive formability of the welded member is provided, even when using a steel sheet having a tensile strength of 980 MPa or more. In a laser welded joint including a first steel sheet, a second steel sheet, and a butt weld between said first steel sheet and said second steel sheet, one or both of said first steel sheet and said second steel sheet is a high strength steel sheet having a tensile strength of 980 MPa or more, and Expression (1), Hs-max - Hs-min £ 200 (1), is satisfied in a heat-affected zone of said high strength steel sheet.
