YD5 65~70% 3.2~4.8mm L280mm tungsten carbide copper welding rod
YD5 65~70% 3.2~4.8mm L280mm tungsten carbide copper welding rod

A.tungsten carbide brazing rods 
 they are ma
de of by sintering tungsten carbide scrap and elastic matrix alloy,Outer layer of the special flux and coloring is marking scrap grade,the composition of sintering tungsten carbide scrap is mainly CO and WC,The hardness is HRA 89~91,tire body matal is Ni and copper alloy,strength can up to 690MPa, hardness HB160.

 

B. Photos show  tungsten carbide brazing rods , 

 

c. tungsten carbide brazing rods usage:                                                          

it 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.

 

 

D. tungsten carbide brazing rods size and grade:                                                                      

there are eight grades according the size of tungsten carbide scrap.

E. overlaying process of tungsten carbide brazing rods,

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.
