Features of homemade laser welding machine

1. It adopts a fully enclosed optical path design, with advantages such as dustproof and good sealing; it can work continuously for a long time (up to 24 hours).

2. The self-developed Wobble welding head is small, lightweight, and easy to operate.

3. It has multiple safety alarm functions. The switch is only activated when the welding copper head contacts the metal, and the safety clamp clamps the metal plate. After removing the welding copper nozzle from the workpiece, the light will automatically lock. The machine has a very high level of safety, ensuring absolute safety for operators during work.

4. Equipped with a 10-meter original fiber optic cable, it overcomes the limitation of workspace on the workbench and enables outdoor welding and long-distance welding.

5. Suntop's patented technology water circulation protection system and auxiliary gas detection effectively extend the life of the laser lens and prevent damage to optical components caused by improper operation.

6. Infrared positioning verifies the position of the welding head during the welding process. The welding position is more accurate, the weld is smooth and beautiful, easy to polish, and no post-welding treatment is required or only simple treatment is needed.

2. Operation interface

Multilingual intelligent control panel, can flexibly adjust welding parameters, multiple sets of welding parameter libraries, cumulative timing of light output, etc.

3. Automatic wire feeding system

Touch screen design, automatic wire feeding, fully digital design, supports 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm diameter stainless steel and aluminum wire.

4. Laser source

Uses a customized minimum 20um core diameter fiber, stronger penetration, laser lifespan up to 100,000 hours, maintenance-free, with Bluetooth function.

5. Chiller

Dual circulation water cooling provides better cooling effect for the laser source and welding head, temperature control sensor uses imported brands.

6. Welding connection fiber

Built-in 10-meter long fiber optic cable design, effectively avoids the problem of fiber optic damage due to moisture, greatly improving the service life of the laser component.

Advantages of homemade laser welding machine

1. The welding speed is fast, being 5-10 times faster than traditional argon arc welding, which can reduce processing costs by about 30%.

2. It is easy to learn and operate, with no technical threshold requirements. Ordinary workers can operate it after a short training, making it easy to achieve high-quality welding results.

3. It is easy to use and flexible, allowing for the adjustment of the work station at any time. There is no need to fix the work station, making it free and flexible. It is suitable for a variety of work environment scenarios for welding.

4. It has a wide welding range, overcoming the limitations of workbench space. It can achieve outdoor welding and long-distance welding.

5. It offers multiple welding methods, allowing for any angle welding, stack welding, butt welding, vertical welding, flat angle welding, internal angle welding, external angle welding, etc. It can handle a variety of complex welding seam workpieces and larger workpieces with non-regular shapes.

6. It has concentrated energy, resulting in a small heat-affected area. There is no deformation or blackening, and it offers a large welding depth. The weld seam is fine and beautiful, with solid welding. The weld strength reaches or even exceeds the strength of the base material itself.

Other optional functions of homemade laser welding machine

Cleaning Function

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be achieved, effectively removing rust, oxide layers, oil stains, etc. from the material surface without damaging its characteristics. It has a non-contact feature, does not require cleaning solution, and can replace professional cleaning equipment.
