What welding methods are suitable for aluminum sheet?

Aluminum Sheet, as a common metal material, can be used in a variety of ways during the welding process. The choice of these methods depends on several factors, including the thickness and shape of the aluminum plate, welding quality requirements, and production efficiency.
Gas shielded welding (GTAW), also known as TIG welding, is a common manual welding method. In this method, the welding area is protected with an inert gas (such as argon) to prevent oxygen and moisture in the air from affecting the welding area. This method is suitable for situations that require high welding quality and appearance. Because the welding molten pool is stable and produces a small amount of spatter, it is often used for precision welding.
Gas metal arc welding (GMAW), also known as MIG welding, is a semi-automatic or automated welding method. In this method, welding is performed using an arc formed by a guide wire and an inert gas or gas mixture. This method is suitable for large-area welding and high-efficiency welding, and is often used in automated production lines in industrial production.
Resistance welding is a welding method that utilizes resistance heating. The two joints of the aluminum plates are connected by heating with an electric current. This method is suitable for thicker aluminum sheets or specially shaped aluminum sheets, often used in specific applications that require a lot of welding.
Plasma arc welding (PAW) is a welding method that utilizes plasma arc heating. In this method, inert gas and plasma arc are used for welding. This method is suitable for high-speed welding and high-quality welding, and is often used in special applications that require high-quality welding.
