Argon arc welding is a kind of arc welding. It uses the burning arc between the continuously fed welding wire and the work piece as the heat source, and the gas shielded arc sprayed from the torch nozzle to carry out welding. However, it has many disadvantages, such as large welding heat affected area, large welding spots, etc. Argon arc welding uses non-consumable electrodes and shielding gas, and is often used to weld thin work pieces, The welding speed is slow, and the heat input is much larger than laser welding, which is prone to deformation; The features of laser welding seam are that the Heat-affected zone is small, the weld seam is narrow, the cooling speed of the weld seam is fast, the performance of the weld metal changes little, and the weld seam is hard. At present, argon arc welding has been gradually replaced by laser welding in precision welding.

The difference between laser welding and argon arc welding is that the technical principles are different.

Laser welding

Laser welding is a type of high-energy beam welding, which is generally using laser welding equipment. Laser welding is a welding process that uses a laser beam focused by high-power coherent monochromatic photon streams as the heat source. The advantage is that it does not need to be carried out in a vacuum and can achieve precise energy control, thus enabling the welding of precision devices. It can be applied to many metals, especially to solve the welding of some difficulties like weld metals and dissimilar metals.

Argon arc welding

Argon arc welding is a kind of arc welding, which mainly uses the burning arc between the continuously fed welding wire and the work piece as the heat source and the gas shielded arc from the torch nozzle to carry out welding. At present, argon arc welding is a commonly used method and can be applied to most major metals, including carbon steel and alloy steel. Melt inert gas shielded welding is suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium, and nickel alloys. Due to its low price, it is widely used for mold repair welding. However, due to the drawbacks of large welding heat affected area and large welding points, laser welding has gradually replaced it in precision welding processes.
