    摘要: A dual-wire hybrid welding system includes a hybrid welding apparatus having laser, electric arc welder and second wire feeding device. Electric arc welder includes first wire feeding device for feeding first wire. Second wire feeding device is arranged and disposed to feed a second wire to electric arc welder. Laser and electric arc welder are arranged and disposed to direct energy toward at least two adjacent components along a joint and first wire is a consumable electrode fed into joint to establish molten pool generated by both laser and arc welder with first wire. Second wire is fed to molten pool to form a common molten pool. Common molten pool is operable to provide a full penetration weld with less total heat input to join the at least two adjacent components without cracking the components at a high constant weld speed.

    摘要: A process for filling openings, including blind holes, through-holes, and cavities, in high temperature components. The process entails forming a powder mixture by mixing particles of at least a base alloy and a second alloy that contains a sufficient amount of a melting point depressant to have a lower melting temperature than the base alloy. The powder mixture is combined with a binder and compacted to form a compacted preform, which is then heated to remove the binder and form a rigid sintered preform. The sintered preform is produced, or optionally is further shaped, to have a cross-sectional shape and dimensions to achieve a clearance of up to 200 micrometers with the opening, after which the preform is placed in the opening and diffusion bonded within the opening to form a brazement comprising the particles of the base alloy dispersed in a matrix formed by the second alloy.
