7 WELIHI OMOITE ROD omposite Rods and Wear ads The composite rods are designed and manufactured to provide you with the highest quality product. They are used in a variety of industries, it is effective in providing protection against wear in many applications. omposite rod is utilized in the following industries: Brick/cement/concrete product manufacturers Down hole reamers, openers, fishing tools oring tools, milling tools, stabilizers crew eders, slurry paddles onstruction industry, Foundry sand mixing Water drilling pecially selected chips of Tungchip either blocky, with sharp edges for cutting applications or rounded Tungchip for wear applications are produced under stringent quality controls. Material is thoroughly cleaned to ensure the best possible wetting properties, both during manufacture and applications. tringent quality control procedures ensure repeatability of excellent quality, low fuming rod. The Tungchip is then blended with as alloy copper Zinc and ckel alloy, to produce a premium quality composite rod. (Matrix designation AW - RB-A). Rod weights vary between 250 gram and 1000 gram with lengths between 300 to 450 mm. omposite rod and wear trays can be supplied in a variety of sizes and shapes. stomer s specific requirements or specials can be produced upon request. Two grades are supplied either BBW, which is for wear applications or BB which is for cutting applications. Rods can be either bare, or flux coated. Only Bare rods are available ex-stock. Flux coated rods can be supplied with a day manufacturing time. ommon sizes (other sizes are produced upon request) 3/16 x 3/8 ( x mm) BBW 3/18 x 5/16 (9.5 x 7.9 mm) BB 5/16 x 1/4 (7.9 x 6.4 mm) BB 1/4 x 3/16 (6.4 x mm) BB 1/16 x 1/8 ( x mm) BB 20 x 30 mesh (0.85 x mm) Flame haracteristics: though a natural flame is preferred for rapid application of omposite Rod, it is best for the inexperienced operator to use a slightly carburising flame. The lower temperature and lack of oxidant will prevent the omposite Rod matrix material from loosing some of its alloying material. omposite Rod materials, which have been overheated exhibit a pocked bubbly surface. While not extremely detrimental to the wear ability of omposite Rod, this condition does somewhat embrittle the matrix and slightly lowers its tensile strength. Technique On leansing: The first important consideration in working with the omposite Rod is cleaning. The areas to be overlaid must be thoroughly cleaned of grease, oxide, scale or other foreign matters. Any method may be used for cleaning which result in an essentially base metal surface. Fluxes will clean metal to a certain extent, but superior results will be evident from thorough precleaning. Flux: Flux serves two main purposes. The first is the removal of foreign elements from the surface to be coated. The second is to prevent oxidation of the surface being coated. If an area is left unfluxed, the torch heat will rapidly oxidize the base material and prevent adhesion of the omposite Rod material. Application: 1) Thoroughly clean the base metal. 2) Lightly heat base material then apply flux. A little heat before applying powdered flux helps it stick to the base materials, as the torch has tendency to blow the flux away. 3) Gently heat the base material to melt flux, observe its coverage and correct any bare spots. 4) Heat base material until it just begins to turn red. At this point begin applying rod to base material. The nickel - silver should flow onto the base material. If nickel - silver balls up the base material is not hot enough, adversely if the nickel - silver runs across the base material it is too hot. are must be taken to maintain the proper temperature of the base material during application. 5) omposite Rod is sluggish and does not flow easily. How it flows can vary considerably, depending on the size and percentage of the tungsten carbide in the rod. Explanation of the exact technique for application is difficult but certain general advice can be given. Work slowly and gently with as little heat as possible. low the omposite Rod to precede the torch rather than follow it. If necessary use the rod as a pushing, packing and smoothing tool while applying just enough heat to melt the matrix. It would probably be beneficial for the beginner to practice on a scrap piece of steel before tackling the actual part to be hard faced. With practice good coatings can easily be made. 7 DITRIBUTED BY:
