A water-cooling fixture for argon arc welding of annular aluminum alloy parts and its working method

Abstract

This invention relates to the field of welding technology, and particularly to a water-cooled fixture for argon arc welding of annular aluminum alloy parts and its working method. The water-cooled fixture includes an upper water-cooling plate and a lower water-cooling plate, with multiple sets of bolt through holes evenly spaced along the circumference of both plates. The part to be welded and the annular plate are clamped in the middle and then secured by bolts. The upper and lower water-cooling plates each have an upper and lower sealed water channel cavity, respectively, which are connected to a cooling water device via hoses. For parts requiring a large welding volume and high dimensional accuracy after welding, this invention, on the one hand, uses bolts to tighten and press the part to be welded, reducing welding deformation. On the other hand, the water-cooled clamping fixture, while pressing and fixing the part, increases the cooling rate, preventing overheating and reducing welding deformation, thereby ensuring the overall dimensional accuracy of the part. The fixture has a simple overall structure and provides good deformation control.
