1.Description

 

YDtype carbide rod (referred YD type electrode), is composed of granular cemented carbide alloy casing with a flexible blend.Coated with a layer of special flux and coloring to identify the size of the particle level. Sintered carbide particles primarily tungsten carbide cobalt.

 

Composition: NCu, tungsten carbide grits

Hardness: >160 HB

TRS: >690MPa

 

2.Application

 

YDcarbide rod    is mainly used for welding petroleum, mining, coal mining, geology, construction and other industries in some serious wear and tear or a combination of cutting parts. Such as: milling shoes, wear shoes, centralizers, reamer, drill pipe fittings, hydraulic cutter, scraper blades, plow iron, core drill bits, hammers drill, screw drill and so on.

overlaying process of tungsten carbide copper Brazing Rod YD-5,

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.
