Phase control method and device for double-wire welding and welding equipment

The invention relates to the technical field of welding, and provides a phase control method and device for double-wire welding and welding equipment. The phase control method for double-wire weldingcomprises the steps that a first phase matching moment in a standard state is obtained according to the set current of a front wire, the set current of a rear wire, first peak time and a first matching coefficient, and the set current of the front wire and the set current of the rear wire are kept unchanged; and a phase matching moment corresponding to the current value is determined according tothe first phase matching moment, the current value and a reference value of the electrical parameter and a set matching coefficient so as to adjust the electrical parameter when the electrical parameter of the front wire or the rear wire meets the set adjusting condition. According to the technical scheme, the welding quality can be improved. 本公开涉及焊接技术领域，提供一种双丝焊接的相位控制方法、装置、焊接设备。本公开提供的双丝焊接的相位控制方法包括：根据所述前丝的设定电流、所述后丝的设定电流、第一峰
