Difference between laser welding and argon arc welding

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

Argon arc welding is a type of arc welding, which uses the arc burning between the continuously fed welding wire and the workpiece as the heat source, and the gas sprayed from the welding torch nozzle protects the arc for welding. However, it has the disadvantages of large heat affected area and large welding spots. Argon arc welding uses non-consumable electrodes and shielding gas, and is often used to weld thin workpieces, but the welding speed is slow, and the heat input is much larger than that of laser welding, which is easy to deform; while the characteristics of laser welding seams are small heat affected zone, narrow weld, fast weld cooling rate, small change in weld metal properties, and hard weld. At present, argon arc welding has been gradually replaced by laser welding in precision welding.

Introduction to both of them :

1. Laser welding

Laser welding is a type of high-energy beam welding, which is generally carried out using laser welding equipment. Laser welding is welding that uses a laser beam focused by a high-power coherent monochromatic photon flow as a heat source. The advantage is that it does not need to be carried out in a vacuum and can perform precise energy control, so it can achieve the welding of precision devices. It can be applied to many metals, especially to solve the welding of some difficult-to-weld metals and dissimilar metals. It has been widely used in mold repair.

2. TIG welding

Argon arc welding is a type of arc welding, which mainly uses the arc burning between the continuously fed welding wire and the workpiece as a heat source, and the gas ejected from the welding torch nozzle protects the arc for 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. MIG shielded welding is suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys. Due to its low price, it is widely used in mold repair welding, but it has disadvantages such as large heat affected area and large welds. At present, it has been gradually replaced by laser welding in the repair of precision molds.
