What is the difference between electric welding, gas shielded welding and argon arc welding?

Electric welding, gas shielded welding and argon arc welding are three common welding methods, and their differences are mainly reflected in the following aspects:

1. working principle: electric welding is a method of melting welding materials and forming weld seams by using high temperature generated by electric arc; Gas shielded welding is to protect the welding area with gas to prevent impurities such as oxygen from entering the weld and ensure the welding quality. Argon arc welding is a method of using argon as shielding gas to form a stable arc and protect the weld.

2. Applicable materials: Electric welding is suitable for welding various metal materials, including iron, steel and aluminum. Gas shielded welding is suitable for welding stainless steel, copper, aluminum and other materials; Argon arc welding is suitable for welding materials such as stainless steel, aluminum and magnesium.

3. Welding quality: high arc temperature, deep melting depth and high welding quality; Gas shielded welding has high welding quality because of gas protection; Because of argon protection, argon arc welding has the highest welding quality.

4. Welding speed: fast welding speed, suitable for mass production; Gas shielded welding is slow and suitable for small batch production; Argon arc welding is slow and suitable for high-demand welding.

5. Equipment cost: the cost of welding equipment is low; Gas shielded welding equipment has high cost; Argon arc welding equipment costs the most.

Generally speaking, the differences among electric welding, gas shielded welding and argon arc welding are mainly in working principle, applicable materials, welding quality, welding speed and equipment cost. In the specific application, it is necessary to choose the appropriate welding method according to the welding requirements and material characteristics.
