Laser welding is to connect two pieces of material together, usually metal material, but laser welding plastic is often used these days.Laser is a single-phase or coherent beam that often appears in sci-fi movies, however, the development of laser beams and their application in laser machine welding makes the use of this highAn energy device that generates heat when it hits the surface.Laser machine welding is used for steam tracking and inspection, surface heat treatment, heating cutting and other precision applications.Laser refers to the interaction of light through the excitation Emission of Radiation, which emits photons in narrow beams.The laser is usually monochrome, which means it emits light at a single wavelength.Public light emits non-coherent light and travels in all directions in the spectrum.In 1960, Hughes lab developed the first working laser, but it was a product of what Einstein did in 1916.However, the laser itself has only recently developed, so the use of laser machine welding is a recent technological innovation.Since the invention of laser, it has been applied in many fields.Modern medicine uses laser to perform surgery, achieving less invasive surgery than in the past.In addition, the fine and precise nature of the laser allows the surgeon to use the laser for fine surgery such as eye surgery.In today\'s practice, many people use laser indicators, especially in the classroom.The shooter uses laser aiming on his rifle.Computer users use laser printers instead of old-fashioned ones.Old-fashioned methods and lasers are used for motion detection and safety in many other applications.Lasers are even used in devices for children\'s toys, office copiers and locks and unlock doors.With the progress of technology, laser has entered all aspects of life, the application of laser in welding technology will naturally appear.The final result of this is the birth of a laser machine --Welding professional, with a place next to Mig, Tig, ARC and other welding methods.Laser machine welding is becoming more and more common in the computer and consumer electronics industry, space and aircraft technology, and defense contractors.Laser machine welding is often used because it is much more accurate than other welding methods.Laser machine welding is usually used for ultra-small-sized micro-welds that are not accessible by conventional welding methods.Laser machine welding is often used in the industry of jewelry manufacturing, engraving, dentistry and tools and molds that require precision.Laser machine welding is the cutting edge of technology, and welders trained in laser machine welding are one of the smartest and most talented welders in the industry.Laser machine welding has also found a home in the high-tech and precise welding requirements of plastic welding.Although plastic welding is usually done with ultrasonic welders, laser machine welding is often the preferred method.
