The utility model relates to the technical field of a welding piece clamping device, in particular to a clamping device for a composite welding process of a welding piece with a substrate plate.

Background technique

As an important connection method, welding is widely used in aerospace, medical equipment, energy and chemical industries. Usually, when welding butt specimens, defects such as welding penetration of butt specimens and poor joint formation are easy to occur. Adding the backing plate under the butting plate can avoid welding through defects, but it will introduce the under-welding defect between the backing plate and the butting plate. When welding butt specimens with backing plates, a single welding method cannot meet the needs of forming a good welded joint. Using a composite welding method, such as TIG + brazing method, can avoid the lack of penetration between the backing plate and the butt plate. , affecting the quality of welded joints. However, in the composite welding process, the substrate plate needs to be coated with brazing material, and then the butt plate is placed on the substrate plate for welding.
