How Does Laser Welding Work? Costs, Advantages & Disadvantages

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.

Consequently, the processing speed is maximized; material costs and operation costs are minimized. This type of laser welding is commonly used in Jewellery, Dental implants,auto industries, transducers, Electronic compo-nents, mobile industries, hardware. W.S.I. is staffed to engineer and perfect the manufacturing quality and price point your looking for. When volumes reach R.O.I. , Weldlogic Inc. will offer you the equipment and developed manufacturing process to ensure a smooth transition into your manufacturing floor.

MORN wobble-IV weld head is perfectly integrated with the fiber laser, providing high-quality welding and surface quality. Wobbling effectively increases beam diameter during laser welding, increasing the width of the weld while maintaining the efficiency of deep keyhole welding. This method of welding enables much easier control of weld parameters such as weld width and depth of penetration which can lead to a more efficient welding process. This is probably the biggest hurdle that stands between this technology and more widespread adoption – laser welders are expensive. This is even more glaring when compared to older welding methods that use gas flames or electrical arcs. The tip of the laser does not need to be close to the material to deliver the power necessary for welding.

Even the most complicated of welding joints can be achieved, including the welding of dissimilar metals. The major advantage of fiber laser welding technology is it is 2 to 10 times faster than any traditional or conventional welding machine. The weld seams are smooth and beautiful and no consumables are needed, thus reducing the subsequent grinding process and saving time and cost. At Markolaser, we set very high standards for quality by rigorous quality control systems, 2 years warranty on complete laser system and excellent after sales service. Its mission is to provide the customers with reliable & precise results acknowledging the highest quality standard demands of the industry.

Plastics of the same type have the highest level of connection stability after laser welding. If the plastic contains a high proportion of glass fibers, this may result in somewhat brittle welding connections. It is therefore recommended that a glass fiber content of 40% is not exceeded. A laser-transparent material with glass fiber should not be thicker than 2 mm.

The welding point penetration and effective penetration decrease with the laser tilt angle. When it is greater than 60°, the effective welding penetration decreases to zero. Therefore, the best choice for welding aluminum alloy is sharp wave and double peak wave. Under the strong vibration of light electromagnetic waves, strong reflected waves and weaker transmitted waves are generated. The reflected waves are not easily absorbed by the aluminum alloy surface, so the aluminum alloy surface has a higher reflectivity to the laser at room temperature. It can be seen that aluminum alloy has the characteristics of high reflectivity to laser light and low absorption rate.

Fiber lasers are now widely used for welding of a very wide range of thicker metals. The near infrared 1070 nm wavelength has definite advantages over the incumbent CO2 laser technology due to the lower reflectivity of metals at this wavelength. This is particularly true for high reflectivity metals such as aluminum and copper where high power fiber lasers are used to weld up to 15 mm, these thicknesses have not previously been welded with other lasers.

The energy of the light photon is absorbed by the atoms of ruby crystal and electrons get excited to their higher energy level. When they return back to their ground state they emit a photon of light. This light photon again stimulates the excited electrons of the atom and produces two photons. In the case of simultaneous welding, the laser beam is formed so that it adapts optimally to the component.

Laser-MIG welding uses a laser beam and an electric arc to work together, resulting in high welding speed, a stable welding process and high thermal efficiency, while allowing for a larger weld assembly gap. Compared to the average speed of 0.5 joints/s for resistance spot welding, the laser remote welding speed is 3 to 4 joints/s, allowing the laser beam to be fully utilized. Using the laser beam as a heat source, the focused beam is directed at the surface of the filled wire. The wire is continuously heated by the beam energy and melts to form a high-temperature liquid metal. The liquid metal is infiltrated into the joint of the part to be welded and, under appropriate external conditions, results in a good metallurgical bond with the workpiece.
