The manual forming of sheet metal processing parts is mainly completed by using some simple tire shapes, molds and various fixtures. Edge, welding seam correction, etc.
The splicing method of sheet metal processing parts: the main workman of sheet metal splicing adopts welding, screw connection and riveting bonding. Commonly used splicing methods: welding, screw connection and riveting.
1. Welding - is the process of applying local or overall heating to the weldment to produce plastic deformation, or heating and plastic deformation at the same time to achieve permanent connection. It can be divided into: manual arc welding, gas shielded arc welding, laser Welding, segment welding and contact welding.
1.1 Gas shielded arc welding - During gas shielded arc welding, the electrode arc area is protected by shielding gas, and the surface of the weld is protected by argon gas without oxides and inclusions. Welding can be performed in any spatial position. 1.2 Contact welding is a welding method that pressurizes the welded part to form a welded joint in the state of instantaneous heating of the connection part (melted state or non-melting) during contact welding, which can be divided into butt welding, spot welding and seam welding.
2. Threaded connection, the threaded connection area is easy to install, disassemble and operate, and is often used for detachable steel structure connections.
3. Riveting, riveting is a method of connecting metal parts together with rivets. There are many types of rivets. rivets, open type countersunk head blind rivets). 4. Bonding, a connection method that uses adhesive to connect the required connections according to the adhesive. But for some special materials, laser cutting is also impossible.
