Abstract
Abstract A welded joint is disclosed having an S-shaped metal connector provided with a first laminate cavity and a second laminate cavity, a first adhesively bonded laminate disposed in the first laminate cavity, and a second adhesively bonded laminate disposed in the second laminate cavity. The first adhesively bonded laminate and the second adhesively bonded laminate, each has a first metal member, a second metal member and an electrically insulating adhesive between the first metal member and the second metal member. The first adhesively bonded laminate and the second adhesively bonded laminate are disposed in the first laminate cavity and the second laminate cavity respectively so that the first metal members and the second metal members are in contact with the metal connector and are welded together.
