Description

technical field

[0001] The invention relates to a control method for double-wire MAG welding and a welding power source thereof, belonging to the field of welding equipment and automation. Background technique

[0002] Twin-wire MAG welding, as a feasible high-efficiency welding method, is still in the development stage. Everyone's understanding of this method is not completely the same, and there is no consensus on some specific issues. From the perspective of the form of the process, there are currently two main types, one is synchronous twin arc (Twin arc), and the other is independent twin arc (Tandem). The process characteristics of these two forms are different. For the form of the Twin arc system, two identical pulse welding power sources are used (only one power source can also be used), two sets of wire feeding mechanisms, and one conductive tip that can accommodate two welding wires (the two wires are not insulated from each other) , sharing a molten pool. When w...
