What is a handheld fiber laser welding machine?

The handheld fiber laser welding machine is a new generation of laser welding equipment, which belongs to non-contact welding. It does not need to be pressurized during the operation. Its working principle is to directly irradiate the high-energy laser beam on the surface of the material, and through the interaction between the laser and the material , so that the material inside melts, and then cools and crystallizes to form a weld.

The hand-held fiber laser welding machine fills the gap of hand-held welding in the laser equipment industry. possible.

Hand-held welding is mainly aimed at laser welding of long-distance and large workpieces. It overcomes the limitation of the travel space of the workbench. The heat-affected area is small during welding, which will not cause work deformation, blackening, and traces on the back. Moreover, the welding depth is large and the welding Firm and fully melted, it can not only realize heat conduction welding, but also continuous deep penetration welding, spot welding, butt welding, lap welding, sealing welding, seam welding, etc.

This process subverts the working mode of the traditional laser welding machine. It has the advantages of simple operation, beautiful weld seam, fast welding speed, and no consumables. It can be welded perfectly on metal materials such as thin stainless steel plates, iron plates, and galvanized plates. Replace traditional argon arc welding, welding of stainless steel plate, iron plate, aluminum plate and other metal materials.

Advantages of handheld laser welding machine

1. Wide welding range: the hand-held welding head is equipped with 5m-10M original optical fiber, which overcomes the limitation of the workbench space and can be used for outdoor welding and long-distance welding;

2. Convenient and flexible to use: Hand-held laser welding is equipped with moving pulleys, which is comfortable to hold and can adjust the station at any time without fixed-point stations. It is free and flexible, and is suitable for various working environment scenarios.

3. A variety of welding methods: welding at any angle can be realized: stack welding, butt welding, vertical welding, flat fillet welding, inner fillet welding, outer fillet welding, etc., and can weld various workpieces with complex weld seams and larger workpieces with irregular shapes. Realize welding at any angle. In addition, he can also complete the cutting, welding and cutting can be switched freely, just change the welding copper nozzle to the cutting copper nozzle, which is very convenient.

4. Good welding effect: Hand-held laser welding is thermal fusion welding. Compared with traditional welding, laser welding has higher energy density and can achieve better welding effect. The welding area has little thermal influence, is not easy to deform, blacken, and has traces on the back , the welding depth is large, the melting is sufficient, firm and reliable, and the weld strength reaches or even exceeds the base metal itself, which cannot be guaranteed by ordinary welding machines.

5. Weld seams do not need to be polished: After traditional welding, the welded joints need to be polished to ensure smoothness and not roughness. The handheld laser welding just reflects more advantages in the processing effect: continuous welding, smooth and no fish scales, beautiful and no scars, less follow-up grinding process.

6. Welding without consumables: In most people’s minds, the welding operation is “goggles in the left hand and welding wire in the right hand”. However, with the hand-held laser welding machine, welding can be easily completed, which reduces the cost of materials for production and processing.

7. With multiple safety alarms, the touch switch is only effective when the welding tip touches metal, and the light will be automatically locked after removing the workpiece, and the touch switch has a body temperature sensor. High safety, ensuring the safety of the operator during work.

8. Labor cost saving: Compared with arc welding, the processing cost can be reduced by about 30%. The operation is easy to learn and quick to use, and the technical threshold for operators is not high. Ordinary workers can go to work after a short training, and can easily achieve high-quality welding results.

Comparison between handheld laser welding machine and argon arc welding

1. Energy consumption comparison: Compared with traditional arc welding, the handheld laser welding machine saves about 80% to 90% of electric energy, and the processing cost can be reduced by about 30%.

2. Welding effect comparison: Laser handheld welding can complete the welding of dissimilar steel and dissimilar metals. The speed is fast, the deformation is small, and the heat-affected zone is small. The weld seam is beautiful, flat, no/few porosity, and no pollution. The handheld laser welding machine can perform tiny open-shaped parts and precision welding.

3. Subsequent process comparison: the heat input is low during laser hand-held welding, the deformation of the workpiece is small, and a beautiful welding surface can be obtained, without or only a simple treatment (depending on the requirements of the welding surface effect). Handheld laser welding machines can greatly reduce the labor cost of the huge polishing and leveling process.

Handheld laser welding machine application field

Mainly for large and medium-sized sheet metal, cabinets, chassis, aluminum alloy door and window frames, stainless steel wash basins and other large workpieces for fixed positions such as inner right angles, outer right angles, and plane welds. The heat-affected area during welding is small, the deformation is small, and the welding depth Large and securely welded. Widely used in kitchen and bathroom industry, home appliance industry, advertising industry, mold industry, stainless steel product industry, stainless steel engineering industry, door and window industry, handicraft industry, household goods industry, furniture industry, auto parts industry, etc.
