  • Butt welding method and friction stir welding tool
    Patent number: 9849541
    Abstract: Provided is a method and tool for butt welding a first material piece of metal to a second material piece of metal at opposed longitudinal edges. The second material piece has a greater material thickness than the first material piece. The first material piece has a higher tensile strength and/or a higher inching temperature and/or a higher yield strength and/or a higher modulus of elasticity than the second material piece. A thickened longitudinal edge is provided at the first material piece. The thickening of the longitudinal edge is at least partly produced by at least simple folding, beading or winding of the first material piece or at least partly by folding the first material piece at its edge. The two material pieces are friction-stir welded at their front along the opposed longitudinal edges.

  • BUTT WELDING METHOD AND FRICTION STIR WELDING TOOL
    Publication number: 20160228980
    Abstract: Provided is a method and tool for butt welding a first material piece of metal to a second material piece of metal at opposed longitudinal edges. The second material piece has a greater material thickness than the first material piece. The first material piece has a higher tensile strength and/or a higher melting temperature and/or a higher yield strength and/or a higher modulus of elasticity than the second material piece. A thickened longitudinal edge is provided at the first material piece. The thickening of the longitudinal edge is at least partly produced by at least simple folding, beading or winding of the first material piece or at least partly by beveling the first material piece at its edge. The two material pieces are friction-stir welded at their front along the opposed longitudinal edges.
