Welding

The laser welding machine can weld special materials such as refractory materials of high melting point metals, and can even be used for welding machines of non-metal materials such as ceramics. It has good effect on welding special materials and has great flexibility. The non-touch long-distance welding machine is applied to the parts that are difficult to access by the welding machine.

Delivering a focused heat source, laser welding creates a strong seam at a high speed. Some of the laser welding machines utilize a 5- or 6-axis control and others utilize a fully articulated wrist. Generally for low thickness of metal like 0.5 to 0.6 mm, it is difficult to weld with traditional technology but with fiber laser welding system it can be done efficiently, cleanly and smoothly. Also aluminium to aluminium welding was a typical task with traditional technology but with this technology; one can do aluminium welding very easily. Because of increase in consumption of fiber source and price war among fiber laser source producers, the price of fiber laser source is coming down. As a result, the prices of fiber laser cutting machine, welding machine, and marking machine are also coming down and they have become truly affordable to anyone.

Germany’s Audi, Mercedes-Benz, Volkswagen, Sweden’s Volvo and other European car manufacturers as early as the 1980s, the first to use laser welding roof, body, side frames and other sheet metal welding. With the continuous development of science and technology, many industrial technologies on the special requirements of materials, the application of smelting and casting methods of manufacturing materials can no longer meet the needs. Under certain laser power and welding speed conditions, the focal point is in the best position when the depth of melt is maximum.

Due to its variable welding temperature, it is relatively insensitive to the individual types of metal. Regardless of whether stainless steel, structural steel, copper or other types of sheet metal are to be welded, laser beam welding masters this task with consistent precision. The only prerequisites are a sufficiently narrow welding gap and precisely set welding temperature and frequency.

By now, you should have a better idea of what you’re looking for and what laser welder would be the right fit for your jewelry studio and jewelry-making practice. If you’re still in doubt, make sure to follow the title links to find out the specific prices, in-depth specifications, and customer reviews about each of our recommendations. Yet another thing to consider is the microscope used in the laser welder machine. While all of our recommendations come with a high-quality Leica® 10X stereo-microscope that allows you a clear, crisp view of what’s happening in the chamber, some cheaper or lower-end laser welders might come with low-quality microscopes. Additionally, higher-end laser welders can also offer control over the height of the microscope and the welding chamber, and they can be adjusted to suit the jeweler’s height.

However, for most applications, helium, argon and nitrogen are often used to protect the workpiece from oxidation during the welding process. In laser deep fusion welding, the laser power controls both the depth of penetration and the welding speed. When the laser power density is near the critical condition of small hole formation, deep fusion welding and conduction welding alternate and becomes unstable welding processes, resulting in large fluctuations in the melt depth. There is a laser energy density threshold in laser welding, below which the depth of melt is shallow and once it is reached or exceeded, the depth of melt increases substantially. The autonomous process cabinet controls the timing of the robot, laser, brazing head, wire feeder and preheating system via the industrial bus to complete the weld. The main production line PLC exchanges signals with the robot via the industrial bus.

@UV laser marking equipment, which has the characteristics of laser equipment, can realize on-line flight marking function on the assembly line, mainly for the shallow marking of thin fragile items such as photovoltaic solar glass, etc. Line part to achieve hierarchical control, increase the time relay to achieve step-by-step power supply galvanometer board, to avoid current supply caused by current fluctuations, impact on the board. We can easily state with absolute certainty that for such high-quality at such price ranges we're the lowest around for CNC Laser Cutting Machine, Portable Laser Welding Machine, Fiber Laser Cutting Systems.

Laser brazing is not suitable for the connection of some components, but the laser can be used as a heat source for soft and hard brazing, which also has the advantages of laser brazing. Welding of different types of metals has to address the range of weldability and weldability parameters. Attention should be paid to the geometry of the wire element during welding. The second function of the shielding gas is to protect the focusing lens from metal vapor contamination and sputtering of liquid droplets. The power density is relatively evenly distributed in all planes away from the laser focal point. The laser and the arc affect the performance of the composite weld in different degrees and forms.

On the one hand to provide additional energy for laser welding, increasing the welding speed and thus the efficiency of the whole welding process. The conversion efficiency of laser welding is generally low (usually 5% to 30%) due to the low absorption of laser light by solid materials, especially after the emergence of plasma . Since laser welding does not require a vacuum environment, remote control and automated production can be achieved through lenses and optical fibers. 4) High processing accuracy due to low average heat input reduces reprocessing costs; in addition, laser welding running costs are lower, thus reducing workpiece processing costs. For example, when hardened steel gears are welded to mild steel drums, proper control of the laser beam position will facilitate the production of a weld with a predominantly low carbon component, which has better crack resistance. Laser welding can be achieved using the continuous or pulsed laser beam, the principle of laser welding can be divided into heat conduction welding and laser deep fusion welding.

At this time, the laser energy should be quickly reduced, and the welding should be performed at a low power to avoid splashing. The laser radiation will cause the base metal to evaporate strongly and form an evaporation groove. The laser beam penetrates into the material through the evaporation groove, and the weld depth and welding efficiency also increase sharply. Once the input power is greater than this value, the transmission of laser energy into the material is no longer limited by heat conduction, and the welding is carried out by deep penetration welding. Such a threshold exists in different aluminum alloy laser welding processing.
