Abstract

The invention provides a twin-wire vertical electrogas welding system with low welding heat input and a welding method. The system comprises a first welding power source, a second welding power source, an integrated power source box, a first wire feeder, a second wire feeder, a first gas shielded welding gun, a second gas shielded welding gun, a gas supply device, a control cabinet, an oscillator and a welding tractor, wherein homopolar output ends of the first welding power source and the second welding power source are in conductive connection with a head end of the first gas shielded welding gun, the other output end of the first welding power source is connected with a welded workpiece, and the other output end of the second welding power source is in conductive connection with a head end of the second gas shielded welding gun, so that heat input is greatly reduced while deposition rate can be increased, the system is stable and reliable, and impact toughness of a welding line is remarkably improved. Additionally, a twin-wire welding gun oscillating in the welding line can guarantee sufficient fusion of side walls of the welding line and a welding weld crater, so that mechanical properties of the welding line are remarkably enhanced.

Description

【Technical field】 [0001] The invention belongs to the field of welding technology, and in particular relates to a low-welding heat-input double-wire vertical gas-electric vertical welding system and a low-welding heat-input double-wire vertical gas-electric vertical welding welding method. 【Background technique】 [0002] The vertical gas-electric vertical welding method based on the metal gas shielded welding technology is an efficient welding method that is very suitable for heavy metal structures, but the biggest problem with these vertical gas-electric vertical welding methods is that the welding heat input is high, and the welding heat input It is proportional to the thickness of the plate, so it greatly limits the scope of application; moreover, the increase of heat input with the increase of the thickness of the plate will reduce the crystallization speed of the weld metal, which will lead to coarse grains, which will lead to the mechanical properties of the weld. The ...
