1.6~3.2mm/3.2-4.8mm/4.8-6.4mm/6.4-8.2mm tungsten cemented carbide copper composite alloy brazing rods
1.6~3.2mm/3.2-4.8mm/4.8-6.4mm/6.4-8.2mm tungsten cemented carbide copper composite alloy brazing rods

A.tungsten carbide composite rod it is made 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 HB≥160.

B. Production time is 7 days

c.tungsten carbide composite rod 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 composite rod size and grade:

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

grade	size (mm)	scrap size (mm)	color
YD-9.5	9.5	9.5~6.5	dark green
YD-8	8.0	8.0~6.5	dark blue
YD-6.5	6.5	6.5~5.0	red
YD-5	5.0	5.0~3.0	yellow
YD-3	3.0	3.0~2.0	pink
YD-10mesh	10mesh	10~18mesh	light green
YD-18mesh	18mesh	18~30mesh	light green
YD-30mesh	30mesh	30~50mesh	light yellow

E. overlaying process of tungsten carbide composite 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.
