Several Joining Methods in Customized Small- and Medium-Scale Sheet Metal Fabrication
03-02
With the continuous upgrading and advancement of production equipment, the vast majority of forming processes are now carried out on automated machinery. Manual methods are typically employed for complementary operations such as finishing and precision machining. However, in single-piece production or when dealing with parts of complex geometries, manual operations and machining remain indispensable. When manual forming of sheet-metal components is performed using simple tire-forming tools, contour-following fixtures, and zero-point clamping systems, the following techniques should be utilized: bending, edge standing, edge sealing, edge drawing, arch bending, hemming, and weld correction, among others.
Today, Suzhou Xuan’er Precision Manufacturing Co., Ltd., a specialist in custom small- and medium-volume sheet-metal fabrication in Suzhou, outlines the primary joining methods used for metal-sheet assemblies: welding, threaded fastening, riveting, and adhesive bonding. Our company exclusively employs welding, threaded fastening, and riveting as our preferred joining methods.
Welding refers to the process of joining workpieces by locally or fully heating them, inducing plastic deformation in the workpieces, or combining both heating and plastic deformation. Welding methods include manual arc welding, gas-shielded arc welding, laser welding, segmented welding, and resistance spot welding. Our company primarily employs gas-shielded arc welding.

Gas-shielded arc welding: During gas-shielded arc welding, the arc zone and the weld pool are protected by a shielding gas, and argon is used to protect the weld surface from oxidation and inclusions. Welding can be performed in any spatial orientation, the weld bead formation can be visually inspected and adjusted, and production efficiency is high.
Spot Welding: A welding process in which, during the welding operation, the workpieces are pressed together to form a weld joint under conditions where the joint material may or may not melt. It can be further classified into butt welding, spot welding, and seam welding.
Threaded Connections: Threaded connections offer the advantages of simple on-site equipment, easy disassembly, and straightforward operation. They are commonly used for detachable steel structural connections and can be classified into screw connections and bolted connections.
Riveting: Riveting is a method of joining metal structural parts or components using rivets. There are many types of rivets. The commonly used rivets include closed round-head blind rivets, closed countersunk-blind rivets, open round-head blind rivets, and open countersunk-blind rivets.
Bonding: The method of joining components by using an adhesive.
