What is the difference between laser welding machine and plasma welding machine!

Laser technology has matured, and laser welding machines have now become one of the mainstream welding equipment. laser welding is to locally heat the workpiece with high-energy laser pulses, and the heat is gradually transferred to the inside of the workpiece, and the workpiece is melted to form a specific molten pool, so as to achieve the purpose of welding.

laser welding is a new type of welding method. It is mainly used for welding precision parts, fast welding for thin plate materials, and basically no deformation of the workpiece after welding. It gradually penetrates into various industries and gradually replaces the traditional plasma. Most of the market for welding machines. So what is the difference between a laser welding machine and a plasma welding machine?

The difference between laser welding and plasma welding is that both belong to general beam arc welding, both of which convert electrical energy into heat energy, can weld materials with high melting point, and can achieve double-sided welding and forming on both sides.

The difference between laser welding and plasma welding is that the laser of the laser welding machine is a monochromatic, specific and coherent photon flow, and the maximum laser power can reach 106-129w/cm2. The Plasma welding machine belongs to the arc that suffers from shrinkage, and the plasma arc is usually 106w/cm2. The maximum temperature that a laser welding machine can reach is much higher than that of a Plasma welding machine. Laser welding equipment is complex and diverse, and the cost is relatively high, while the Plasma welding machine has a simple structure and relatively low cost.

The application environments of the two are different. Laser welding is mainly used in industries with high precision requirements such as automobile bodies, locomotive tracks, medical machinery, and electronic products. Plasma welding machines are mainly used in manufacturing, such as copper alloys, titanium alloys, carbon steel, stainless steel, aluminum and other fields commonly used in large-scale industrial production where precision requirements are not high.
