Advantages of laser welding using various technological approaches, including an additional feed of a filler wire, deposition of thin layers of flux on base metal, decrease in focal distance of the lens and application of periodic-pulse modulation of the laser beam, are considered.
Keywords: laser welding, thin-sheet steels, special approaches, flux, filler wires, focal distance, continuous and periodic-pulse radiation, welding speed, microstructure, microhardness
