What is the difference between argon arc welding and laser welding?

Laser welding and arc welding are two commonly used methods for mold repair. Argon arc welding argon arc welding is a kind of arc welding, which uses the arc combustion between the welding wire and the workpiece as the heat source and the gas sprayed from the nozzle of the welding gun to protect the arc. At present, argon arc welding is a common method, which can be applied to most major metals, including carbon steel and alloy steel. Metal inert gases are suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys. Because of its low price, it is widely used in mold repair welding. However, due to the shortcomings of large heat affected area and large solder joints, laser welding has been gradually replaced in the repair of precision molds. Laser welding Laser welding is a kind of high-energy beam welding, which uses a laser beam focused by a high-power coherent monochromatic photon stream as a heat source. This kind of welding party
