| description | A tube welding rod resistant to high stress abrasion is used for hard facing of an abrasion-resistant layer, and comprises a welded tube and a filler filling the welded tube. The filler comprises, in weight percentages, 65-90% of spherical sintered tungsten carbide particles, 5-30% of spherical cast tungsten carbide particles, 0-15% of mechanically ground cast tungsten carbide particles, 2-6% of alloy power, and 0.2-1% of an organic binder. The used of the mixed spherical sintered tungsten carbide particles and the spherical cast tungsten carbide particles improves the abrasion resistance performance of the hard-faced layer in the high stress working condition, improves the overall abrasion resistance of the abrasion-resistant hard-faced layer formed by the welding rod, and is suitable for surface hardening of bits. |
