For some countries, you might also need the transformer to provide 380 voltage for the laser welder GY-WF2000 which is the optional you can consult our sales. Wobble welding gun can realize 5 mm large beads welding, it allows a wider seam or a rough edge of material.
All products realize spot welding, straight seam welding, overlap welding, circumferential welding and welding of any track. Compared with traditional argon arc welding, the efficiency is increased by more than 50%. In many ways, laser welding seems like the sensible next level of evolution from traditional welding techniques like gas flame and electrical arc. The equipment is a little more expensive, but laser welding is undoubtedly more energy-efficient, faster, and more precise. More importantly, laser welding machines are designed to run automatically, which is a crucial element in modern manufacturing. The high power density of lasers makes them capable of welding materials that would have been challenging for other welding techniques.
Preventing thermal cracks is one of the key technologies for laser welding of aluminum alloys. In order to improve the quality of the weld seam, continuous laser welding is used. The weld seam surface is smooth and uniform, free of spatter and defect, and no cracks are found in the weld seam.
Scholars at home and abroad have begun to use high-power semiconductor lasers for welding research on aluminum alloys. Therefore, helium, which does not produce plasma, is often used as the shielding gas for high-power CO2 laser welding. It generally works in a continuous manner, has a high output power and is widely used in high-power laser welding. High-quality joint strength and large depth-to-width ratio can be obtained with laser welding, and the welding speed is relatively fast. Laser deep fusion welding usually uses continuous wave CO2 lasers, which can maintain a high enough output power to produce a “small hole” effect, melting through the entire cross-section of the workpiece and forming a strong welded joint.
Applications are corner welds on the visible surfaces of device housings. Now that you’ve read our reviews, you may still be wondering which laser welder is the right option for your jewelry studio. Read on to find out which factors to consider before you commit to a laser welder. Probably the biggest drawback for some people would be the large and heavy build of this laser welder, which makes the model unsuitable for small studios.
In addition, you have the option of including the Machineseeker Trust Seal on your homepage and in business letters. The financing round, the company’s largest to date, aims to increase adoption of its blue industrial laser technology. This article tries to examine whether the decoupling will happen and to what extent , and how it will impact the laser industry. A palm-sized, battery-powered industrial power meter that requires no water or fan cooling is able to measure laser powers from 200 mW to 8 kW. For plastics with thicknesses in the 0.2–5 mm range, a source with 2–3 µm wavelength may be used to make conventional butt joints and other joint configurations.
Laser hybrid welding increases the geometric size of the molten pool through the coupling of the laser beam and the arc, and changes the flow conditions of the material in the molten state, which is beneficial to the elimination of pores. In addition, in laser welding of aluminum alloy, the faster the welding speed, the more likely it is to crack. In the aluminum alloy welding process, some low-boiling elements (Mg, Zn, Mn, Si, etc.) are easy to evaporate and burn. The slower the welding speed, the more serious the burning, which changes the chemical composition of the weld metal. For highly reflective materials, such as aluminum alloys and copper alloys, it is necessary to provide a very large power density during welding. Based on some characteristics of the aluminum alloy itself, the laser welding process is more complicated, and it is urgent to improve and perfect.
For example, you may want to repair a worn mold feature with a harder material than the base metal to improve its wear resistance over the original. Combined, all the advantages of pulsed laser welding allow Phoenix to deliver repaired molds that perform as well as when they were brand new. With a conventional welding process, the material in that zone becomes softer and more likely to wear.
Among aluminum alloys, the 6000 series Al-Mg-Si alloys are especially sensitive to cracks. Usually, crystal cracks appear in the weld zone, and liquefaction cracks appear in the near-joint zone. During the instantaneous solidification of the alloy, the solubility of hydrogen decreases sharply when it changes from liquid aluminum to a solid state. If the excess hydrogen in the liquid aluminum cannot smoothly rise and overflow, it will form hydrogen pores. In addition, the presence of cracks and pores in the weld leads to a decrease in tensile strength.
