China Gantry Plasma Spray Welding Machine for Wear Plate

This series of plasma spray welding equipment is mainly used to spray all kinds of reinforced wear-resisting layer on large plate. Control system adopts programmable controller to complete the program control, on the color touch screen input and regulation to control spray welding process parameters. System can store 100-200 menu of spray welding technology, when spray welding according to work piece model call directly relevant parameter menu can reappear the process parameters of storage. Can also according to the state of molten pool in the process of spray welding conveniently adjusting the parameters of the corresponding. Equipment control panel also equipped with digital display instrument for non-transferred arc, transferred arc voltage and current, can monitor the most important parameters of welding voltage and current. Touch screen display intuitive, can display parameters, easy to adjust the display interface, according to the control requirement of programming convenient, flexible, suitable for small batch and many varieties spray welding. Adpots gantry span and guide rail length can be designed according to customer's requirements; can satisfy the different length and width of the flat spray welding requirements. Welding torch can move along the span of gantry direction around. Welding torch move along the track and frame which move around adopt stepper motor driver, can be precisely set both directions of movement speed and distance, ensure accuracy of lap welding layer. Double welding torch spray welding at the same time, domestic initiation than conventional double single gun spray welding production efficiency. Torch cooling adopts high-power cold water machine, stable work, can work continuously for 3-4 hours of arc. Spray welding plate welding layer thickness, overlapping precision, surface is flat and level.
The machine is mainly used in high quality large flat surface spray welding. After surface hardness can reach HRC58-60, within the scope of the 1000 x1000 weld layer does not crack, not obvious deformation. Can work out a complete plane without defects, can be used in the manufacture of rolling mill bearing high hardness skateboard.
