[0002] In the process of tableware forming, the front and back halves of the tableware need to be welded together, and then polished to form a new whole after welding. This split production can reduce the cost of direct forming and save raw materials. For small pieces of raw materials, stamping can be fully utilized. If directly formed, some of them need to make specific molds due to their special shapes, and the cost is too high. Especially for tableware produced in small batches, the cost of developing molds is too high. For example, in the process of small-batch production, the handle and head of the table spoon need to be welded. In order to ensure the strength and aesthetics of the welding, the welding of the handle and the head is an irregular shape. At present, mechanical welding can be used for straight-line welding, and most irregular shapes are welded manually, which has high strength and low efficiency. Summary of the invention
