What are the differences between laser welding machine and plasma welding machine?

Laser welding machine, also often called laser welder and laser welder, is a machine used for laser material processing. Laser welding is the use of high-energy laser pulses to locally heat the material in a tiny area, and the energy of laser radiation spreads to the interior of the material through heat conduction, melting the material and forming a specific molten pool.

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

The application of laser welding machines is becoming more and more widespread, gradually penetrating into various industries. And with the market demand, laser welding machines are slowly replacing plasma welding machines. So, what is the difference between laser and plasma welding machines?

Laser welding machine

Analysis of the differences between laser welding machine and plasma welding machine:

1. laser welding and low-temperature plasma arc welding similarities

Laser welding machine and plasma welding machine are attributed to the general beam arc welding; heating temperature is high, can electric welding for welding high melting point raw materials; both can be connected in a small round hole can be carried out as well as electric welding welding, keep single double-sided welding two sides of the development of molding.

2. laser welding and low-temperature plasma arc welding difference

Plasma welding machine low-temperature plasma arc is mainly attributed to this contraction of electrons, while the laser belongs to the monochromatic, single specificity and dry photon flow; maximum temperature of heating is also much higher than the low-temperature plasma arc, the particle beam is very easy to focus, dissipate and guide, can be connected with CNC machinery or intelligent robots, non-contact production processing, easy to improve, laser welding equipment complex, cost increases, low-temperature plasma arc welding mechanism Simple and low cost.

3. laser for welding and low temperature and the use of plasma arc welding technology welding

Laser welding is widely used in automotive, rail locomotives, large machinery, shipbuilding, aerospace, medical machinery and other industries; low-temperature plasma arc welding for the manufacture of copper and alloy copper, titanium and titanium metal, carbon steel, stainless steel plate, molybdenum and other common metal materials used in aerospace and titanium cruise missile casing, thick-walled vessels and other top industrial production technology.
