Laser welding machine, also known as laser welding machine and laser welding machine, is a kind of machine for laser material processing. Laser welding is the use of high-energy laser pulse to heat the material in a small area. The energy of laser radiation is guided to the internal diffusion of the material through heat transfer, and the material is melted to form a specific molten pool.

Laser welding is a new welding method, mainly used for thin-walled materials, precision parts surface welding, can realize spot welding, butt welding, stack welding, seal welding, etc., depth width ratio is small, welding width is small, thermal impact area is small, deformation is small, welding speed is fast, welding flat, beautiful, welding without treatment or simple treatment, welding quality is good, no pores, precise control, aggregation Small focal point, high positioning accuracy, easy to realize automation.

The application scope of laser welding machine is more and more wide, and gradually penetrated into various industries. And with the market demand, laser welding machine is slowly replacing plasma welding machine. So, what's the difference between laser welding machine and plasma welding machine?

Laser welding machine

The difference between laser welding machine and plasma welding machine is analyzed

1. Similarity between laser welding and low temperature plasma arc welding

Laser welding machine and plasma welding machine belong to the general beam arc welding; heating temperature is high, electric welding can be used to weld high melting point raw materials; can be carried out in the way of small round hole connection and electric welding, keep the development of single and double sides welding.

2. Difference between laser welding and low temperature plasma arc welding

The low temperature plasma arc of plasma welding machine is mainly attributed to the shrinking electrons, while the laser belongs to monochromatic, single specific and dry photon flow; The heating degree of the maximum temperature is also much higher than that of low temperature plasma arc. The particle beam is very easy to focus, dissipate and guide. It can be connected with CNC machinery or intelligent robot. It is easy to improve the non-contact production and processing. The laser welding equipment is complex and the cost is increased. The low temperature plasma arc welding mechanism is simple and the cost is low.

3. Application of laser welding and low temperature and plasma arc welding technology

Laser welding is widely used in automobile, rail locomotive, large machinery, shipbuilding, aerospace, medical machinery and other industries; low temperature plasma arc welding is used to manufacture copper and alloy, copper, titanium and titanium metal, carbon steel, stainless steel plate, molybdenum and other commonly used Aerospace metal materials, and titanium cruise missile shell, thick walled vessels and other top industrial production technology.
