Abstract
Technology of automated multi-pass laser and laser-arc welding of structural steels with thickness of up to 20 mm is described. Productivity of the hybrid welding method is several times higher compared with laser welding.
Keywords: laser welding, filler wire, consumable electrode, hybrid process, thick carbon steels, number of passes, conditions, heat input, metallography, structure, hardness, impact toughness
