Thesis is focused on verification of suitability of Laser-TIG technology for penetrating welding of galvanized sheets, made of WSS M1A 365-A14 50G steel and DC01 steel. Electric arc functions here as a preheating for evaporation of zink layer. Electric current was chosen as a variable parameter of magnitudes 0, 20, 30 and 40 A. Test welds were made, which have been subjected to a tensile test and metallographic evaluation. The positive influence for electrolytically galvanized steel WSS M1A 365-A14 50G was registered and determination of optimal welding parameters was successful. The electric arc also had a positive effect on welding of hot-dip galvanized steel DC01, but at the selected test parameters not enough to achieve a reliable connection.
