Laser welding is a precise joining technique that uses a focused beam of light to melt and fuse materials together. This method is commonly used for metals and thermoplastics, providing strong and clean welds with minimal distortion. The high energy density of the laser allows for deep penetration and fast processing speeds. One of the key advantages of laser welding is its ability to automate the process, making it suitable for mass production. Additionally, it can be used in various industries, including automotive, aerospace, and electronics, where high-quality welds are essential for performance and safety.
