The welding jig in the prior art usually includes an upper jig and a lower jig. The workpiece to be welded is placed between the upper jig and the lower jig. Thereafter, a clamp such as a C-clamp, a dovetail clamp, etc. is used to apply an upper and lower force to ensure that the workpiece to be welded is fully fitted. However, this clamping method is relatively cumbersome. It not only requires a large number of operators but also requires matching corresponding cylinders and other driving components. The assembly time is long and the efficiency is low. Therefore, it is urgent to propose a welding jig that can quickly apply an upper and lower force to the upper jig and the lower jig.

Thereafter, the workpieces are put into the welding furnace for welding. After welding is completed, the upper fixture and the lower fixture can be quickly separated, and the workpieces can be taken out for quality inspection. No additional clamps (such as C-type clamps or dovetail clamps) are required throughout the process, which significantly improves processing efficiency.
