Product Description

 

Description:
1. YD Tungsten carbide composite welding rod is made of cemented carbide tips and Ni/Ag(Cu)alloy. The carbide tips always be tungsten carbide crushed grits, carbide wear inserts, like the carbide star shape inserts, carbide pyramid shape inserts, shark shape inserts and so on. Sometimes, the carbide tips can be tungsten carbide powder. The economy choice is tungsten carbide crushed grits. If you want to higher durable than carbide grits, carbide inserts is better. However the cemented carbide/crushed carbide with sharp edge has excellent wear resistance and cutting ability too.

2. The hardness is 89-91 HRA, we have two types of YD rod,the matrix alloy is mainly made from Cu,Zn or Cu,Zn,Ni(9-10%),Ni will make welding rods work better with more adhesion,so the rods with Cu,Zn,Ni matrix alloy will be more expensive than the rods without Ni.

3. In brief, most of the Composite rod made using crushed sintered Tungsten Carbide grains bonded with a bronze nickel matrix,(Cu 50 Zn 40 Ni 10) with a low melting point ( 870°C ).

4.It is mainly used to overlay the worn-out and cutting usage workpieces in oil&gas,mining,coal mining,geology,contruction and other industries, such as:milling shoes,wear shoes,centralizers,reamer,drill pipe joints,hydraulic cutter,scrapper blade plow planer,drill core,piling drilling,auger etc.
 

The grain sizes of the carbide grits:
1. 1/8-1/16 in. ( 3.2-1.6 mm )
2. 3/16-1/8 in. (4.8-3.2 mm)
3. 1/4-3/16 in. (6.3-4.8 mm)
4. 3/8-5/16 in. (9.5-7.9 mm)
5. 5/16-1/4 in. (7.9 -6.3 mm)
6. 3/8-1/4 in. (9.5-6.3 mm)
7. 1/2-5/16 in. (12.7-7.9 mm)
 

The grades of the composite rods:There are main grades depends on the different Proportion of the tungsten carbide grits

Sizes, unit weight, grits sizes can be OEM.

Composite welding rod has been used in 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.YD tungsten carbide rod 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.
