Advantages of hg500tm 4 in 1 handheld metal laser welding machine

1. High precision and high quality

Handheld laser welding equipment has the characteristics of high precision and high quality. Due to the high focus of the laser beam, the welding process has high energy density, resulting in a small heat-affected zone and good welding quality. At the same time, the welding accuracy of handheld laser welding equipment can reach about 0.2mm.

2. Fast welding speed

Compared to traditional welding methods, handheld laser welding equipment has a very fast welding speed, mainly due to the high power of the laser beam. During the welding process, the laser beam can quickly scan the weld seam and complete the welding task rapidly. This undoubtedly improves production efficiency and reduces production costs.

3. Not limited by materials

It can weld almost all metal materials, including stainless steel, carbon steel, aluminum alloy, etc. Therefore, it can meet a wide range of application needs.

4. Not limited by space

The laser welding machine and welding gun are integrated together, and the handheld laser welding equipment can be conveniently moved to perform various welding tasks, whether indoors or outdoors, whether on flat or curved surfaces.

5. Easy operation

The operation is simple and easy to learn, with no technical threshold for operators. Ordinary workers can start operating after a short training, and can easily achieve high-quality welding results. Laser welding does not require secondary polishing, saving a lot of labor costs.

Remark: Double weld thickness can be achieved if the material is welded from both sides in two times.

Uses of laser welding machines

With the continuous development of laser welding technology, the use of laser welding machine is more and more extensive.

1. Welding: laser welding machine main welding object for the metal, such as stainless steel, copper, aluminum, gold, silver, titanium, nickel, tin, chromium, niobium, carbon steel, mold steel, galvanized sheet, etc., suitable for plane, straight line, arc, and any shape of the weld, multi-angle to carry out the welding work to meet the user's personalized welding needs.

4. Weld channel cleaning: can effectively remove the welding process generated by the oxides, welding slag, oil, dust and other impurities, so that the weld surface becomes clean. This not only helps to improve the quality of the weld, but also enhances the strength and appearance of the weld. Laser cleaning is highly accurate and controllable, allowing the weld surface to be thoroughly cleaned without damaging the base metal.

Comparison between handheld laser welding machine and argon arc welding

1. Energy consumption comparison

Compared with traditional arc welding, handheld laser welding machines save about 80%-90% of electric energy, and processing costs can be reduced by about 30%.

2. Comparison of welding effects

Laser handheld welding can complete the welding of dissimilar steels and dissimilar metals. Fast speed, small deformation and small heat affected zone. The welds are beautiful, smooth, with no/little pores, and no pollution. Handheld laser welding machines can perform tiny open parts and precision welding.

3. Comparison of subsequent processes

The heat input during handheld laser welding is low, the deformation of the workpiece is small, and a beautiful welding surface can be obtained without or only simple processing (depending on the welding surface effect requirements). Handheld laser welding machines can greatly reduce the labor costs of huge polishing and leveling processes.
