FIELD: process engineering.
SUBSTANCE: invention relates to machine building and may be used in welding different materials by laser radiation. Plane of but joint between said parts is inclined along tangential line to segment of welded seam thermal effect. Laser radiation is focused to material with higher heat resistance at a distance from butt plane. But joint plane inclination angle and focus distance are determined with due allowance for inhibiting evaporation of low-melting metal. Laser radiation is fed onto welded surfaces to heat welding zone to melting temperature to produce, thereafter, a welded seam.
EFFECT: possibility to weld different metals together.
