The basic principle of https://www.angelo-home.com/product/40012/ is the use of high-energy, focused light to fuse metal pieces. The laser is powered by a high-voltage power supply, while a lens focuses the beam directly onto the area to be welded. A computer program, known as CAM, controls the speed of the laser and the workpiece table. The power output of the laser is controlled by the CAM, which controls how fast the table rotates and how far the beam travels.
There are two main types of lasers: solid-state and fiber-based. In solid-state https://www.hmlasercutter.com/product-category/laser-welding/, a high-powered laser vaporizes the base metal to create a tunnel. This tunnel forms a keyhole, which enables the laser to penetrate deep into the metal. Gas lasers use a mixture of gases, such as carbon dioxide, nitrogen, and helium, and can operate in either continuous or pulsed modes.
In contour welding, the laser beam travels along a surface in a sequential manner, melting part tolerances while melting a larger area. Unlike other forms of welding, contour welding requires a smaller volume of work to create the optimum joint. During this process, the joining surface is traversed several times per second, and the melted metal is then solidified when the laser heat source is removed. This process can be used to join smaller parts without worrying about the resulting gap.
Another important aspect of laser welding is its high depth-to-width ratio. Because the laser beam is small, the smallest parts can be welded with very little thermal distortion or damage. The precision of laser welding allows for better consistency and lower scrap rates. The main drawback of laser welding is that the cost of the welding equipment is much higher than for other types of welding. But if you’re a small-scale manufacturer, laser welding can be an effective solution.
While it can be difficult to find the right combination of power levels for a specific project, the benefits far outweigh the drawbacks. Depending on the project, a laser is the most effective method for welding thin-sheet metals. For larger-scale projects, a continuous-wave laser is more appropriate, since it is more powerful and has the ability to penetrate deeper than the pulsed laser. The advantages of laser welding include higher welding speed, smaller HAZ, and increased microstructure compared to MIG welding.
Automotive parts are also a great place for laser welding. These parts are typically made of thin sheet metal, including aluminum or non-ferrous metals. This means that they cannot tolerate a lot of heat. The frames of cars contain many hard-to-reach points. As a result, welds on these parts need a higher level of finish, including being attractive and neat. The precision of laser welding makes this technology a preferred choice.
As the number of industrial laser welding machines continues to grow, the cost of these machines increases. This technology is ideal for small and medium-sized facilities. Its efficiency and high speed make it a popular choice in manufacturing plants, universities, and other settings. It is also extremely fast and is highly aesthetic. The precision of these machines makes it possible to fully automate welding processes, resulting in increased production and cut down on expenses. If you are considering a laser welding project for your next project, it might be a smart move.
