A kind of particulate-abrasion-resistant and drilling-wear-resistant tubular built-up welding electrode with high hardness 2. Filled up with the homogeneous mixture of hard phase tungsten,tungsten compound and other metal additions 3. Built-up welding by brass solder,metallurgical joint is formed between built-up welding metall and the welded metal.Espectially suitable for built-up welding of petrobeum-exploiting and mining tool(for example:steel-tooth drill) and mechanical parts that is subject to strong abrasion of rock and sand Product & Application Grade Specification Padding Application HTZ1 Φ4×600 Φ5×600 Φ6×600 Hard phase:Cast tungsten carbide Grain size options: 60-80(mesh) 40-60(mesh) 30-40(mesh) 20-30(mesh) Surface built-up welding in metallurgy ,construction,grain and edible oil processing ,road construction,mining industries etc.,such as on material blender,high speed sand mixer,mill blade,bump shell,excavator blade, hammer etc.and mining tools. HTQA Φ3.2×600 Φ4.0×600 Φ5.0×600 Sintered WC/super-hard WC composite material High wear resistance and impact resistance,specially used for surface built-up welding of petrobleum,gas prospecting tool.   Note:Normally Φ4×600 is supplied unless otherwise specified.Cautions as welding: 1.Preheating the part to 450℃-650℃ according to part shape size and material. 2.Light carbonization blaze welding. 3.Control matrix metal temperature to melting point when welding,then cool slowly after welding.
