lasersvejsning

Lasersvejsning is a welding process that uses a laser beam as the heat source. The focused laser beam melts the material in a localized area, and as the beam moves, the molten material solidifies, creating a strong bond. This process offers high power density, allowing for very rapid welding speeds and narrow heat-affected zones, which minimizes distortion and material degradation.

The laser beam can be precisely controlled, enabling intricate and precise welds, making it suitable for welding thin materials or for applications requiring high accuracy. Lasersvejsning can be used on a wide range of metals, including steel, aluminum, titanium, and copper alloys, as well as some plastics. The process can be performed in atmosphere, under vacuum, or with shielding gases to prevent oxidation.

Key advantages of lasersvejsning include its speed, precision, minimal thermal distortion, and the ability to weld dissimilar materials. It also offers good penetration and can be automated, making it an efficient choice for mass production. However, the initial equipment cost can be significant, and safety precautions are necessary due to the high-intensity laser beam. Applications are found in industries such as automotive, aerospace, medical devices, and electronics manufacturing.
