Abstract: A method for welding a metal part with a laser that generates a laser beam, where the method includes manually feeding successive portions of a filler material adjacent the metal part and in a pathway of the laser beam, generating the laser beam for melting the filler material, and cooling the melted filler material for fusing the filler material to the metal part. The method further includes controlling an intensity of the laser beam based on a sensed position of a user's hand relative to the laser beam.

Abstract: Brazed structures (10) comprising hollow components (12) having a closure component (14) bonded thereto by a metallic brazing alloy (16) for closing off an end of the hollow component (12) are disassembled by locating a wire transport material (20) in the hollow component (12) and covering the open face of the hollow component with a wire fiber material (22). Heat is then applied to liquefy the brazing alloy (16) which is drawn up into the metal wire fiber material (22) by capillary affect created by the wire transport material (20).
