Laser machine welding is the joining of two pieces of material, usually metal, but often plastics these days, using a laser beam. A laser is a single phase or coherent beam of light often seen in science fiction movies, but the development of the laser beam and its application in welding with laser machines allows advances in precision welding using this high energy device. , which generates heat when it hits the surface. Laser machine welding is used for steam inspection and tracing, surface heat treating, heat cutting, and other precision applications.

The laser, which stands for light amplification by stimulated emission of radiation, emits photons in a narrow beam. Laser light is generally monochromatic, meaning it emits light of only one wavelength. Ordinary light emits incoherent light, which goes in all directions of the spectrum. The first working laser was developed by Hughes Laboratories in 1960, but descended from the work done by Albert Einstein in 1916. However, the laser itself is such a recent development that the use of laser welding is quite a technological innovation. recent.

Lasers have found applications in many areas since their invention. Modern medicine uses lasers for surgery, realizing the ability to perform less invasive surgical procedures than in the past. Furthermore, the fine and precise nature of lasers has led surgeons to use them for operations as delicate as eye surgery. In common practice, many people today use laser pointers, especially in the classroom. Shooters use laser sights on rifles. Computer users use laser printers for output instead of old methods, and lasers are used for motion detection and security, among many dozens, if not hundreds, of other applications. Lasers are even used in children’s toys, office copiers, and devices used to lock and unlock car doors. As technology improved, lasers found their way into all aspects of life and it was only natural that applications of lasers to welding technology would occur. The end result of this has been the creation of the specialty laser machine welding, taking its place alongside Mig, Tig, Arc and other welding methods.

Uses for laser welding are becoming common in the computer and consumer electronics industry, in aeronautics and space technology, and with defense contractors. Laser machine welding is often used because it can be much more precise than other welding methods. Laser machine welding is often used for micro-welds of very small dimensions that conventional welding methods could never touch. Laser machine welding is often used in jewelry making, engraving, dentistry, and the tool and die industry where precision is demanded. Laser machine welding is at the forefront of technology, and welders trained to use laser machine welding are some of the brightest and most talented welders in the industry.

Laser machine welding has also found a home in the highly technical and precise welding needs of plastic welding. While plastic welding is often done with ultrasonic welders, laser welding is often the preferred method.
