Abstract

Equipment for laser welding complex, which can apply to machine-building, aerospace, shipbuilding, and automobile industries, has been designed and manufactured on the basis of technique for automated laser welding of flat tubes made of copper-nickel alloys. A method for controlling the integrity of welded flat tubes has been developed. It implies the pressure tests and the search of defective sections by laser interferometry technique in automated mode. A specialized welding head has been designed and manufactured for industrial application of laser welding technique.
Keywordscopper-nickel alloys, laser welding, marine heat exchangers, pulse-modulated radiation, slitting compounds
