The advantages of the forming process of Stainless Steel Weld Elbow are mainly reflected in the following aspects: no tube blank is needed as raw material, which can save the cost of tube making equipment and molds, and can obtain push elbows with any large diameter and relatively thin wall thickness. The raw materials of this stamping elbow are relatively special, and no tube blank raw materials need to be added, which is easy to control during processing. The blanks for processing stamping elbows are flat plates or developable surfaces, so the material cutting is simple, the accuracy is easy to ensure, the assembly and welding are convenient, the raw materials are easy to control during processing, the operation is relatively simple, there are no complicated processes, and welding and assembly are relatively convenient. Due to the above two reasons, the manufacturing cycle can be shortened and the production cost is greatly reduced. Because no special equipment is required, it is particularly suitable for on-site processing of large stamping elbows. The forming process of stamping elbows is complicated, and welding needs to be performed according to different materials and uses, and gradually formed under relative pressure. The forming of stamping elbows needs to be carried out according to relative procedures and strictly abide by the corresponding process, otherwise the stamping elbows produced will have quality problems. According to the needs, a circular ring shell can be cut into 4 90° elbows or 6 60° elbows or elbows of other specifications. This process is suitable for manufacturing large push-made elbows of any specifications with a ratio of the elbow middle diameter to the elbow inner diameter greater than 1.5D. It is an ideal method for manufacturing large push-made elbows. This process molding method is used in the production of different elbows and shows good use value in different fields, making the process have good value in the production of different elbows.
