Abstract

The invention belongs to the technical field of welding and provides a novel twin-wire bypass coupled arc efficient metal-inert gas (MIG) welding system. By the adoption of the twin-wire bypass coupled arc efficient MIG welding system, the problems that an existing twin-wire bypass coupled arc efficient MIG welding system is complex in structure and high in cost are solved. The twin-wire bypass coupled arc efficient MIG welding system comprises a welding power source and a dynamic voltage adjusting device. The dynamic voltage adjusting device comprises an invert unit, a filtering unit, a voltage transformation unit and a direct-current output unit. The invert unit is used for inverting direct currents output by the positive electrode of the welding power source into alternating currents. The filtering unit is used for filtering current higher harmonics output by the invert unit in the inverting process. The voltage transformation unit is used for converting the output voltage of the invert unit into the voltage equivalent to the compensation amount of the bypass voltage. The direct-current output unit is used for rectifying the alternating currents output by the voltage transformation unit into the direct currents and outputting the direct currents. Due to the fact that the welding system comprises the welding power source, the system structure is simplified, and the welding cost is reduced.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a high-efficiency MIG welding system with double-wire bypass coupling arc. Background technique [0002] Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics. Metalinert-gaswelding (MIG welding) refers to a welding method that uses the arc heat generated between the molten electrode (welding wire) and the workpiece to be welded to melt the base metal under the protection of an inert gas. [0003] High efficiency, high quality and low consumption are the urgent requirements put forward by the current manufacturing industry for welding technology, and it is also the direction of welding technology development. At present, there are many new twin-wire high-efficiency MIG welding methods, such as Tandem and Twins welding methods. However, Tan...
