1500w hand-held laser welding machine is a new type of welding method, mainly for the welding of thin-walled materials and precision parts, which can realize spot welding, butt welding, stitch welding, sealing welding, etc. Small affected area, small deformation, fast welding speed, smooth and beautiful welding seam, no need or simple treatment after welding, high welding seam quality, no pores, controllable, small focusing spot, high positioning accuracy, easy to realize automation .

The laser welding machine works by emitting a concentrated beam of light that is focused on the area to be welded. The laser heats up the metal to its melting point, causing it to fuse together with the other metal being welded. The machine is equipped with a control system that allows for precise control over the welding parameters, such as power, speed, and pulse duration. The 1500w hand-held laser welding machine is commonly used in industries such as automotive, aerospace, and jewelry manufacturing. It can be used to weld a variety of metals, including stainless steel, aluminum, and titanium.

• Welding material: stainless steel, carbon steel, galvanized sheet and other metals;

 

1500w hand-held laser welding machine parameters:

1. Power density: Power density is one of the key parameters in laser processing. With higher power densities, the surface layer can be heated to the boiling point in the microsecond time range, resulting in a large amount of vaporization. Therefore, high power density is beneficial for material removal processes such as punching, cutting, and engraving. For lower power density, it takes several milliseconds for the surface temperature to reach the boiling point. Before the surface vaporizes, the bottom layer reaches the melting point, which is easy to form a good fusion weld. Therefore, in conduction laser welding, the power density is in the range of 104~106W/cm2;

2. Pulse waveform: Pulse waveform is an important issue in welding, especially for sheet welding. When a high-intensity beam hits the surface of the material, some of the energy on the metal surface will be reflected and lost, and the reflectivity varies with the surface temperature. During the action of a pulse, the reflectivity of the metal changes greatly;
3. Pulse width: Pulse width is one of the important parameters of pulse welding. It is not only an important parameter that is different from material removal and material melting, but also a key parameter that determines the cost and volume of processing equipment;
4. Influence of defocus amount: Because the power density in the center of the spot at the laser focus is too high, it is easy to evaporate into a hole. The power density distribution is relatively uniform across the planes away from the laser focus. There are two defocusing methods: positive defocusing and negative defocusing. The focal plane above the workpiece is positive defocus, otherwise it is negative defocus. According to the theory of geometric optics, when the distance between the positive and negative defocus planes and the welding plane is equal, the power density on the corresponding plane is approximately the same, but the shape of the molten pool obtained is actually different. When the defocus is negative, a larger penetration depth can be obtained, which is related to the formation process of the molten pool.

Working principle of hand-held laser welding machine:

Laser welding is to use high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of 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. Small deformation, fast welding speed, smooth and beautiful welding seam, no need or simple treatment after welding, high welding seam quality, no pores, controllable, small focusing spot, high positioning accuracy, and easy to realize automation.
