What materials can the handheld laser welder machine weld and what are the advantages of the handheld laser welder?

With the continuous development of science and technology, traditional welding methods cannot meet the special requirements of materials in many industrial technologies. The advantages of handheld laser welder are low bonding strength and wide heat-affected zone, which has gradually replaced traditional welding methods in many industries. Compared with traditional welding equipment, handheld laser welder has stronger functions, higher reliability, more convenient operation without vacuum conditions, and a wider variety of materials that can be welded.
1.Laser welding steel
Carbon steel is a very common metal material, widely used everywhere in life. Welding carbon steel with laser welder for steel will give better results. When welding carbon steel with different carbon content, the welding torch can be slightly shifted to the side of the low-carbon workpiece to ensure the quality of the joint. Due to the very fast heating and cooling rates during laser welder for steel welding, weld crack and notch susceptibility increases as the carbon content increases when welding carbon steels. Both medium and high carbon content steels and common alloy steels can be laser welded well, but preheating and post-weld treatment are required to relieve stress and avoid cracks.
2.Laser welding stainless steel
Welding of stainless steel is easier than conventional welding to obtain high-quality joints. Due to the high welding speed and small heat-affected zone of laser welding, the overheating phenomenon and the adverse effects of large linear expansion coefficient during stainless steel welding are reduced, and the weld seam has no defects such as pores and inclusions. Compared with carbon steel, stainless steel is easier to obtain deep penetration narrow welds due to its low thermal conductivity, high energy absorption rate and melting efficiency. Welding thin plates with low-power laser welding stainless steel machine can obtain joints with good appearance and smooth and beautiful weld seams.
3.Laser welding aluminum
The biggest difficulty in welding aluminum sheets to aluminum sheets with aluminum laser welding machine is that it has a high reflectivity to the laser beam. Aluminum is a good conductor of heat and electricity, and its high density of free electrons makes it a good reflector of light. The initial surface reflectivity exceeds 90%, that is to say, deep penetration welding must start at less than 10% of the input energy, which A very high input power is required to ensure the necessary power density at the start of welding.
4.Advantages of BuyCNC handheld laser welder
Labor saving, fast speed, high efficiency, low cost; easy to learn operation, low requirement for handheld laser welder operator experience, no need for skilled welders, easy recruitment, workers can carry out welding operations after basic training, and novices can also produce beautiful welds seam
The continuous laser beam quality of laser welding stainless steel aluminum steel machine is good, the energy density is high, the welding speed is more than 2 times that of solid YAG laser welding, and 3-5 times that of argon arc welding, which can save at least 2 welders and 1 grinder a year;
handheld laser welder is an integrated design, the laser, water tank, and control part are integrated together, which occupies a smaller area and has low requirements for the site. It is equipped with moving pulleys, and the station can be adjusted at any time according to site requirements, which is convenient and flexible.
