Abstract
The invention relates to the technical field of fuel tank manufacturing, and discloses fuel tank welding equipment and a welding technology.The fuel tank welding equipment comprises a pressing mechanism and a welding mechanism, the pressing mechanism comprises a pair of clamps oppositely arranged in the first direction, and the two clamps are suitable for pressing or loosening two shells; the overturning driving device is suitable for driving the pressing mechanism to rotate in the horizontal direction, so that the opening of a part of the splicing seam of the two shells faces upwards; the rotation driving device is suitable for driving the clamp to rotate in the circumferential direction in the first direction; and the welding device comprises a laser welding gun and a tig welding gun and is suitable for welding a splicing seam with an upward opening, and an interval is formed between the two clamps. According to the fuel tank welding equipment, laser tig hybrid welding is adopted, efficient welding is achieved through the mutual coupling enhancement effect of electric arcs and laser, and a laser device with small power can be selected to reduce the cost; and the clamp circumferentially rotates around the first direction, so that continuous annular welding seam welding is realized, and the welding efficiency and the welding quality are favorably improved.
