Application of carbide composite welding rod
                                                                                                                                                    

carbide composite welding rod is mainly used for surfacing welding the oil, mining, coal mining, geology, construction and other industries in some serious wear and tear or artifacts of both cutting.Such as: milling shoes, grinding, centralizer, reamer, drill pipe joints, hydraulic cutter, scraper, plough planer knives, core bit, piling drill, twist drill, etc.






Production process of carbide composite welding rod
                                                                                                                                                    

The oxyacetylene butt, the operating process is as follows:

(1) clean up the workpiece, make the welding workpieces surface with metallic luster.

(2) the flat position of welding, therefore can use the appropriate clamping fixture for control of surfacing layer thickness, thick piece of available.

(3) with a neutral flame preheating, flame core not contact surface, the distance to 25 mm is advisable.

(4) carbide surfacing welding layer.With YD type electrode surfacing, the use of neutral flame (can be slightly carbonizing flame) tip is steady on the workpiece surface movement, the flame of the alloy electrode heating (be careful not to make flame cone tip contact alloy particles), tire body in the electrode alloy melt, carbide particles are also falling.Before the tire body of molten metal solidification, the particles arrange, can use left hand of the alloy electrode fingers, or another person holding a base electrode or pull rod on graphite rod in a quick stir particles, making them evenly aligned neatly.Surfacing layer thickness control according to the requirements of design.

(5) after the workpiece welding, where no ventilation, slow cooling, cannot quench, conditional usable asbestos blanket cover.

(6) the workpiece after cooling to room temperature, if necessary, grinding surface surfacing to required size and shape.

(7) clean up the workpiece, remove all splash, slag, etc.

Packing and shipping of carbide composite welding rod
                                                                                                                                                    

step 1, wrapped carbide composite welding rod in paper to avoid carbide composite welding rod to broke
step 2, put the carbide composite welding rod in inner small carton box
step 3, put the inner box into outter carton and fill the carton with foamed plastic
step 4, wrap the carton with packaging tape
step 5, you can choose any delivery way such as DHL,TNT,UPS ect.
