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 material, as the torch has a tendency to blow the flux away.
3. Gently heat the base material to melt flux, observe its coverage and correct any bare spots.
4. Applying a coating of Tungchip Tinning Rod can assist in the adhesion of the Composite Rod to the base material. The tinning rod can also be used to fill voids and give a smooth appearance if required.
5. Heat base material until it just begins to turn red. At this point begin applying rod to base material. The Tungchip Tinning Rod should flow onto the base material. If the Tungchip Tinning Rod balls up, it is not hot enough. Adversely, if the Tungchip Tinning Rod runs across the base material it is too hot. Care must be taken to maintain the proper temperature of the base material during application.
6. Composite Rod is sluggish and does not flow easily. How it flows can vary considerably, depending on the size and percentage of the Tungchip Tungsten Carbide Grit 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. Allow the Composite 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 parts to be hardfaced. With practice good coatings can easily be made.
