Composite Welding Rod with Copper matrix alloy: Composite Welding Rod with nickel matrix alloy:
AWS: RBCuZn-A AWS: RBCuZn-D
Composite rod welding has been acknowledged throughout oil drilling, mining and construction industry worldwide for its extra hardness and high wear resistant properties. The use is even spreading to more industries and gets greater uses. Composite rod welding has wear and cutting properties coupled by high-end weld ability and low fuming, allowing the material to use in stabilizers, reamers, drill pipe joints, construction drilling, hydraulic-cutter, pipe cutter blades, core bit, scraper, twist drill, milling and grinding shoes etc.
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.
