Sheet metal welding is the technique of joining thin metal sheets together by high temperature or pressure, and is often used to create complex metal structures and components. During welding, the workpiece is heated to the melting point to form a molten pool, which is solidified into a weld after cooling.
Due to the thin thickness of sheet metal, the welding method needs to consider factors such as material thickness, welding strength, and appearance. Sheet metal welding is widely used in automotive, aviation, construction and home appliances and other industries. In addition to welding, sheet metal connection methods include riveting, bonding, and threading. Sheet metal welding enables product engineers to connect individual metal parts to form complex functional structures.

Features: Suitable for thin metal plate welding, solder joint is small and firm. No filler material required, high welding efficiency. Applied in mass production, high degree of automation. Application: Mainly used in automobile manufacturing, home appliance industry and sheet splicing.
Principle: The use of high-energy laser beam irradiation sheet metal, instant heating melting metal, forming a weld. Features: Narrow weld, small heat affected zone, less deformation. High speed, precise welding, suitable for fine machining. Good effect for refractory materials (such as aluminum, stainless steel). Application: Used for high-precision and high-strength welding requirements, such as electronic equipment, precision mechanical parts and so on.
Principle: The high-temperature flame produced by the combustion of acetylene and oxygen is used to melt the metal for welding. Features: The equipment is simple and suitable for low cost and low requirement welding tasks. Suitable for repair and welding of thin sheet and small parts. Application: Often used in thin metal maintenance and small manual welding occasions.
Principle: The use of plasma arc welding, energy concentration, narrow weld and high precision. Features: Small heat affected zone, suitable for high precision and large thickness metal welding.

The welding process is usually carried out at high temperatures, so that the metal workpiece is partially melted and connected to the welding part and then cooled to form a strong connection.
Including gas shielded welding, spot welding, laser welding, etc., different welding methods are suitable for the material and thickness are also very different.
The welded joint usually has a high strength, which is generally close to or even higher than the strength of the raw material itself.
Welding can form a heat affected zone on the surface of the metal, where the material can change, affecting strength and corrosion resistance.
The welding quality is not only strong, but also needs to meet specific needs in terms of product appearance and durability.
After the product is welded, the welded joint will form an integrated structure, suitable for high strength and complex adaptability.
Compared to other connection methods, the welding process does not produce additional material waste.
Can be used in different metal materials and their alloys, widely used in steel, aluminum, stainless steel and other metal connection.
Welding is suitable for workpieces of various shapes and sizes, and large or local areas can be connected.
Compared to other connection methods, such as riveting or threading, welding requires lower tool and material costs and higher production efficiency.
