Welding method and device

The invention discloses a welding method and equipment. The welding method comprises the following steps: controlling a magnet exciting coil to generate a magnetic field at a joint of a workpiece; a welding gun is used for conducting arc ignition in the magnetic field to preheat the workpiece; and a stirring piece is controlled to conduct stirring friction welding on the preheated joint so that the workpiece can be melted and the joint can be welded. According to the welding method, the welding speed is higher, the production efficiency is higher, and the production cost can be effectively reduced. 一种焊接方法及设备，焊接方法包括：控制励磁线圈在工件的接缝处产生磁场；使用焊枪在所述磁场内引弧预热所述工件；控制搅拌件在预热后的所述接缝处进行搅拌摩擦焊接，以使所述工件熔化而熔接所述接缝。上述焊接方法的焊接速度更快，生产效率更高，还能够有效降低生产成本。
