What are the main welding methods commonly used by sheet metal workers during producing custom aluminum box and custom metal boxes ?

Arc Welding

   The heat generated by the arc discharge is used to melt the electrode and the workpiece and form a weld after condensation to obtain a firm joint.

Gas Welding

   Use the flame to heat the metal and the welding wire at the joint of the metal workpiece to melt them to achieve the purpose of welding. The commonly used combustible gases are mainly acetylene, liquefied petroleum gas and hydrogen, etc., and the commonly used combustion-supporting gas is oxygen.


   Using a metal material with a lower melting point than the base material as brazing material, the solder and brazing material are heated to a temperature higher than the melting point of the brazing material and lower than the melting temperature of the base material, and the liquid brazing material is used to wet the base material, fill the joint gap and diffuse with the base material to realize the method of joining the solder.

Carbon Dioxide Gas Shielded Welding

   A method of welding using carbon dioxide gas as a shielding gas, which is simple to use and suitable for automatic and full-face welding. It is suitable for indoor work because there is no wind during welding.

Submerged Arc Welding

   Submerged arc welding is a welding method in which the arc is burned under the protective layer of the welding machine, the arc is burned under a layer of granular fusible flux cover, the arc light is not exposed, the arc is covered by flux and air isolation, no arc radiation during welding, reducing the damage to the operator's body.
