Laser cladding machine adopts servo motor for transmission with precise movement, which can be used for welding of carbon steel, stainless steel, aluminum and other metals, motor shafts and cylindrical workpieces (CO2/MAG/MIG, laser and other welding methods), therefore it is widely used in automotive, motorcycle, fire-fighting, electromechanical, renovation, and other fields. An airbag clamping mechanism is adopted to press or reset the workpiece, which can be controlled automatically for easy loading and unloading of the workpiece. Its control system uses LS programmable logic controller (PLC) as the main control system, supplemented by relay control, which realizes the automatic control of welding process. The operator can set the welding speed and other parameters directly through the operation interface to meet the needs of production.
