摘要： Two thin plate members preferably made of metallic sheets are prepared and one end surface of at least one of the members is formed so as to have an inwardly curved recess which constitutes a gap when the end surfaces of the members are linearly butted together. A laser beam is irradiated along the butted portion of the members. The gap may have various forms having a predetermined width. The two members to be butt-welded may be substituted by two end portions of a single metallic sheet having a rectangular configuration in the case where a shell portion of a can is formed by the butt-welding operation.
