Abstract

The invention provides a dynamic twin-wire three-arc welding method, belonging to the technical field of welding. The invention solves the problem that contradictions exist between improvement of deposition rate and reduction of heat input in the existing arc welding methods. The method is characterized in that a wire feeder is adopted to automatically feed a first welding wire and a second welding wire into two welding wire tips respectively and the included angle between the two welding wires is ensured to be 0-90 degrees; one output end of a first variable polarity power source is connected with one welding wire tip; one output end of a second variable polarity power source is connected with the other welding wire tip; after being connected with each other, the other output end of the first variable polarity power source and the other output end of the second variable polarity power source are connected with a workpiece to be welded; and the phase difference between output signals of the first variable polarity power source and the second variable polarity power source is 180 degrees. The welding method is efficient.

Description

technical field [0001] The invention relates to a double-wire dynamic three-arc welding method, which belongs to the field of welding technology. Background technique [0002] Due to the rapid increase in the consumption of metal structures, especially large metal structures, in key industries related to social development such as modern energy, construction and transportation, the manufacturing industry is increasingly dependent on welding technology, which mainly involves arc welding technology . This has resulted in an increase in the welding workload and an increase in the labor cost of welding production. Therefore, higher and higher requirements have been put forward for welding production efficiency. High-efficiency welding has become one of the key technologies that the manufacturing industry is most concerned about. At present, due to the wide use of high-strength steel materials, the improvement of the dimensional accuracy requirements of metal structures and the ...
