Welding is a commonly used joining process in sheet metal manufacturing. The connection between metal parts is achieved by heating the metal material to its melting point and applying pressure. This article will introduce in detail the welding processes commonly used in sheet metal manufacturing, including common welding methods, process characteristics and application scope, to help readers better understand and apply this key process.

1. Welding method:

a. Arc welding: The high temperature generated by the arc melts the welding material to form a connection. Common arc welding methods include manual arc welding, gas shielded arc welding, etc.

b. Gas shielded welding: Use inert gas (such as argon) or active gas (such as carbon dioxide) to protect the welding area during the welding process to prevent oxygen and water vapor from contaminating the weld and improve the welding quality.c. Welding cladding: The welding material is melted and deposited on the surface of the workpiece to form a covering layer to improve the wear resistance, corrosion resistance and other properties of the workpiece.

2. Process characteristics:

a. Flexibility: The welding process is suitable for workpieces of various shapes and sizes, and has strong applicability and flexibility.

b. Efficiency: Fast welding speed and high production efficiency, suitable for large-scale production and batch processing.

c. Connection strength: The welded connection has high strength, good sealing and stability of the connection point, and can withstand large tensile and shear forces.

3. Scope of application:

a. Automobile manufacturing: Welding connections of automobile bodies, chassis and other structural parts.

b. Electronic equipment: Welding processing of electronic equipment casings, radiators and other parts.

c. Machinery manufacturing: Welding processing of structural parts and spare parts of mechanical equipment.

4. Summary:

Welding technology plays an important role in sheet metal manufacturing and is widely used in various fields. By rationally selecting welding methods and parameters and controlling welding quality, efficient and stable welding processing can be achieved, providing a reliable connection method for sheet metal manufacturing.
