Tungsten composite rods/YD welding rods are made of matrix alloy and carbide grits. Surface is coated with a special flux and colored to identify the particle size and grade. They are used for cutting and wear parts in mining, oil drilling, geology and building industries such as wear shoes, lifter, enlarger, drill pipe joints etc.
Carbide Composite Rods Features
1. rease the wear resistance properties
2. Protect the surface of tools subject to abrasive wear
3. rease the speed of downhole milling and cutting,maintaining full guage on stabilizers, guides keyseat wipers, and other downhole tools.
Carbide Composite Rods Applications
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.
