FIELD: process engineering.
SUBSTANCE: invention relates to combined arc welding. Multiple electrodes are used for gas-arc welding and hidden-arc welding. For first electrode of gas-arc welding by metallic electrode, welding wire features diameter of 1.4 mm and larger while current density in this case makes 320 A/mm2 or higher.
EFFECT: ruled out deterioration of thermal influence area impact strength in metal sheet welding.
