Tpw-1500w/2000w 4-in-1 Handheld Metal Laser Welding Machine

Laser welding uses high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation is diffused into the material through thermal conduction, and the material is melted to form a specific molten pool. It is a new welding method, mainly aimed at welding thin-walled materials and precision parts, and can realize spot welding, butt welding, stack welding, sealing welding, etc. It has a high thickness ratio, small weld width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful weld, no need or simple post-welding treatment, high weld quality, no pores, precise control, small focused spot, High positioning accuracy.

Use of laser welding machine

1. Welding

The main use of laser welding machine is undoubtedly welding. It can weld almost all metal materials and can complete welding well in various complex environments. It has high production efficiency and has more obvious advantages than traditional argon arc welding, electric welding and other processes. When welding, the production efficiency is high, which has more obvious advantages than traditional argon arc welding, electric welding and other processes.

Using a laser welding machine, the welding seam width is small, the depth is large, the thermal shock area is small, the deformation is small, the welding seam is smooth and beautiful, the welding quality is high, there are no pores, it can be precisely controlled, the welding quality is stable, and no processing or simple processing is required after welding.

2. Cleaning

With the continuous reform and upgrading of laser welding machines, they have more and more functions. They can not only weld and cut, but also clean and remove rust. The laser welding machine uses the beam emitted by the laser to eliminate the pollution layer on the surface of the workpiece being processed. Cleaning using a laser welding machine is non-contact and does not require cleaning fluid. It can replace professional cleaning equipment.

3. Cutting

Laser cutting is a new cutting method. The laser welding machine can be used to cut stainless steel, carbon steel, aluminum, aluminum alloy, iron and other metal sheets. The maximum cutting thickness is about 2mm.

4. Weld seam cleaning

In addition to the above three functions, our laser welding machine can also clean the weld seam. Laser cleaning can effectively remove oxides, welding slag, oil, dust and other impurities produced during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances its strength and appearance. Laser cleaning is highly precise and controllable, thoroughly cleaning the weld surface without damaging the base material.

Handheld laser welding and argon arc welding comparison

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

2. Comparison of welding effect: Laser handheld welding can complete the welding between metal and dissimilar metal. Fast speed, small deformation, small heat-affected zone. The welding seam is beautiful, flat, without/less porosity and no pollution. Handheld laser welding machine can perform tiny open parts and precision welding.

3. Comparison of subsequent processes: Handheld laser welding with low heat input and small deformation of the workpiece can result in a beautiful welded surface without or with only a brief treatment (depending on the welded surface effect requirements). Handheld laser welding machine can greatly reduce the huge polishing and leveling process consuming labor costs.
