Laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts, and can realize spot welding, butt welding, stitch welding, sealing welding, etc. Laser welding machines are widely used in various industries with the advantages of high efficiency, good effect, high precision, and easy automation integration. At present, it has been fully utilized in aerospace, health care, 3C digital, auto parts, mechanical meal gold, new energy, bathroom hardware and other industries.

 

 

How Does The laser welding machines Work?

The pump source supplies the medium with energy. It stimulates the laser in a way that the electrons in the molecules are temporarily lifted to a higher energy state.
The electrons in the stimulated state cannot remain there as they drop drastically to a lower energy level.
They give off a photon as they lose the excess energy they get from the pump. It’s known as impromptu emission and the photons created by this process are the seed for the production of a laser.
The photons are given off by the impromptu discharge. Lastly, they hit other electrons present in the elevated energy states. When an approaching photon “knocks” the electron from the stimulated state to a lower level of energy, another photon is formed. These photons are consistent. It implies that they’re in phase, has a similar wavelength, and are moving in the same direction. The procedure is referred to as stimulated emission.
Photons are given off in every direction. Nonetheless, some of them move lengthwise to hit the vibrator mirrors, which bounce back via the medium. The vibrator mirrors determine the preferred amplification direction for the exciting discharge. There has to be a greater atoms percentage in the stimulated form than the lower energy levels for amplification to take place. This population inversion of excess atoms in the stimulated state causes several conditions needed for the generation of a laser.
The laser’s concentration spot is directed towards the workpiece surface which you’re welding. The concentration of light energy transforms into heat (thermal) energy at the surface. The heat makes the material thaw. It advances via the surface through a procedure known as surface conductivity. The gleam level of energy stays below the evaporation temperature of the workpiece material. The perfect thickness of the materials you’re welding should be 20mm. The energy of the laser is concentrated. It’s a benefit if you’re working with materials with high thermal conductivity.

Laser welding is a true revolution in the world of industrial welding . It offers great advantages when working, it allows welding at high speed and to obtain resistant and precise welds. But before buying a laser welder, it is interesting to know more about these machines.

Handheld laser welding machine can be widely used in cabinets, kitchens, staircases, elevators, racks, ovens, stainless steel doors and windows guardrail, distribution boxes, stainless steel home and other industries complex and irregular welding process.
