| Wire Description: TWP70 is a flux cored wire electrode for open-arc welding. Macrocrystalline tungsten carbide, nickel and boron fill a pure nickel tube which can be welded with or without shielding gas. Macrocrystalline tungsten has a higher melting point than that of the molten welding puddle, therefore the matrix is not affected by the degradation of Tunsten carbides throughout the matrix. The result is a stable matrix which is not brittle and can absorb impact without cracking. Key Performance Characteristics: Highest abrasion resistance, Highest impact resistance, Uniform carbide distribution throughout weld deposit, Crackless weld deposit Applications:TWP70 can be applied on ferritic and austenitic steels using a open or
closed arc welding procedure, with or without gas shielding. TWP70 is used to overlay and protect areas which are exposed to the most extreme abrasion and/or impact. TWP70 has been used for diamond bit augers, cement factory fan blades, bucket teeth, and crusher rolls. Information provided by Trimay® |
