Laser technology brought with it the need for a higher standard of services provided by traditional welding machines. The manual/portable welding machines used in the industry help professionals with forms developed over decades. Laser welders must fit into this already established system. Today, this has been achieved on an industrial level, but the different technology still solves welding tasks in a different way in some cases than traditional welding. The main elements of laser welders are the welding gun, which is responsible for the oscillating movement of the laser light, the laser source, water cooler, wire conveyor, auxiliary gas management and control, and the entire system is controlled by a controller. Compared to traditional technologies, laser welders consume less energy, the speed of seam formation can be higher and the quality of the welding seam is also better. Carbon steel, stainless steel, aluminum, copper alloy can be welded.
