What Are The Several Welding Methods Available?

Welding, as an important connection processing method, has a wide range of applications in industrial production. Here are several common welding methods:

Welding rod arc welding: This is a traditional welding method that involves manually operating the welding rod for welding. It is suitable for welding various metal materials, thicknesses, and structural shapes.

Submerged arc welding (automatic welding): This method involves the combustion of an arc under the flux layer, and is suitable for welding parts with small horizontal positions or inclination angles. It is widely used in fields such as shipbuilding, boilers, bridges, etc.

Carbon dioxide gas shielded welding (automatic or semi-automatic welding): a melting electrode arc welding method that uses carbon dioxide as a shielding gas, suitable for welding materials such as carbon steel and alloy steel.

MIG/MAG welding (melting inert gas/active gas shielded welding): MIG welding uses inert gas as the shielding gas, while MAG welding adds a small amount of active gas to the inert gas. These two methods are suitable for welding various metals such as stainless steel, aluminum, copper, etc.

TIG welding (tungsten inert gas shielded welding): Welding is performed using the arc heat generated between the tungsten electrode and the workpiece under inert gas protection. This method is suitable for welding metals such as aluminum, magnesium, and titanium.

Plasma arc welding: Using a water-cooled nozzle to restrain the arc, a high-energy density plasma arc is obtained for welding. It is suitable for welding stainless steel, aluminum, copper and other metals.

Resistance welding: This is a welding method that uses resistance heat as an energy source, including spot welding, seam welding, projection welding, and butt welding. It is suitable for welding thin plate components with a thickness less than 3mm.

Electron beam welding: Welding is performed using the heat energy generated when a concentrated high-speed electron beam bombards the surface of a workpiece. This method is suitable for welding high-quality products.

Laser welding: Welding is performed using a laser beam focused by a high-power coherent monochromatic photon flow as a heat source. It is suitable for welding precision microdevices.

The above are some common welding methods, each with its specific application areas and advantages. In actual production, choosing the appropriate welding method is crucial for ensuring welding quality and improving production efficiency.
