Handheld Laser Welder Laser Welding Machine Price

The handheld laser welder is a new generation of laser welding equipment, which belongs to non-contact welding. Its working principle is to directly irradiate a high-energy intensity laser beam on the surface of the material, and through the interaction between the laser and the material, The material is melted inside, and then cooled and crystallized to form a welding line.

Parts of a handheld laser welder：

1. Laser welding server

The server key of the laser welding machine creates a laser beam for welding. It is composed of switching power supply, laser generator, part of laser optical path, automatic control system and other main parts.

2. Refrigeration system

The key of the refrigeration system is to provide heat dissipation for the laser generator. Generally, it is equipped with 1-5 water circulation system industrial chillers with output power.

3. Laser welding automatic console

The system is used to complete the laser welding. The laser light of the laser welding machine moves according to the specified standard according to the welding trajectory to complete the full-automatic welding of the laser. Generally, the product workpiece exercises and the laser head is fixed; Laser head fitness exercise, product workpiece fixed; Or the laser head and product workpiece move these three motion control system modes; All system software, according to the form of CNC program writing, write the fitness management program to operate the console to exercise according to the requirements. Moreover, through the optimized program writing system software, the actual operation is simple and the operation steps can be grasped quickly.

4. Fixture tooling

In the production process of laser welding machine, laser welding fixture tooling is the key to fix the product workpiece for fixed welding, and enable it to be repeatedly loaded, unloaded, transported and accurately positioned, so as to facilitate the full-automatic laser welding. Therefore, fixture is one of the equipment in laser welding production and manufacturing.

5. Observation system software

Generally, the laser welding machine needs to be equipped with observation system software, which can also realize real-time microscope observation of products, so as to facilitate accurate positioning and detect the actual welding effect in the whole welding process when customizing the welding procedure process. Generally, it is equipped with CCD display equipment or optical microscope.

Putting the Welder to Work

Fisher said response to the laser welding system has been positive. The technology stands out because it’s much smaller than other “portable” units produced overseas, which are about the size of a small refrigerator, and helps even novice welders get up to speed more quickly than they would with more traditional arc welding processes. For instance, laser welding doesn’t impart as much heat as TIG welding does, which makes it easier for a less experienced welder to take on a job with thin metals. In another example, welders don’t have to be as concerned with prebrushing or grinding down the work surface because laser welding doesn’t require the metal to be as clean as would be needed with the MIG welding process. Additionally, the built-in cosmetic pass feature provides a fast and noncontact method to improve postweld aesthetics, and an upcoming surface cleaning option will provide preweld surface preparation anywhere on the material surface.

How Does It 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.
