This invention relates to the field of aluminum alloy welding technology, specifically a dual-gun synchronous magnetron welding process for long aluminum alloy vehicle body components. The process includes setting a first GTAW welding torch on the front side of the workpiece and a second GTAW welding torch on the back side, with the tungsten electrode tips of the two torches offset along the weld direction. The first GTAW welding torch is equipped with a first magnetron coil, and the second GTAW welding torch is equipped with a second magnetron coil. The first and second alternating magnetic fields operate in opposite phases. This invention controls the phase relationship of the two alternating magnetic fields, causing the front and back magnetic fields to operate in opposite phases. This allows the two magnetic fields to act at staggered times, avoiding the superposition and enhancement effect of magnetic fields. When using the opposite-phase scheme, the front magnetic field promotes the front arc to swing to the left during the positive half-cycle, while the back magnetic field causes the back arc to swing to the corresponding side during the negative half-cycle. The two arcs are staggered in time, and their respective magnetic lines of force do not superimpose in the same direction, thus suppressing arc interference.
