Development of Technology and Equipment of the Automated Laser Welding for Manufacturing Heat Exchanger Details of Marine Engines

Section: Scientific and Technical Innovative Projects of National Academy of Sciences of Ukraine
Language: Ukrainian
Abstract: Based on the developed automated laser welding technology for flat tubes of copper-nickel alloys laser welding complex technological equipment, which can be applied on the enterprises of machine building, aerospace, shipbuilding and automobile industries, was designed and created. To control the integrity of welded flat tubes a technique, which consists in testing sample pressure and finding defective sections by laser interferometry in the automated mode, was developed. Specialized welding head was designed and manufactured for the industrial use of the developed laser welding technology.
Key words: marine heat exchangers, copper-nickel alloys, laser welding, slitting compounds, pulse-modulated radiation.
