  • Reduced heat input keyhole welding through improved joint design
    Patent number: 5183989
    Abstract: An improved high energy density welding method for reducing input keyhole welding prepares the weld joint (8) between two edges (10, 14) of at least one member by separating the edges (10, 14) of the member (12, 16) with a controllable gap (22) by a projecting portion (24) selectively positioned on one edge (10, 14) of the member (12, 16). The projecting portion (24) closely abuts the other edge of the member for maintaining the controlled distance (d) of the controllable gap (22) to enhance the welding method.

  • Method of reducing microfissuring in welds having an austenitic stainless steel alloy base metal
    Patent number: 4465224
    Abstract: Prior to welding, a base metal of an austenitic stainless steel alloy is cooled to approximately -78.degree. C. This process, using a conventional filler metal, reduces microfissuring in welds.
