ELECTRODES PASTE FOR BUILD-UP WELDING

摘要

The coating comprises marble, fluorite, rutile, quartz, talc, mica, ferrochrome, ferroboron, tungsten, nickel, cobalt, graphite, carboxy methylcellulose, and liquid sodium silicate. The respective contents are 28-34, 18-25, 10-15, 2-3.5, 2-3, 1-2, 3-12, 0.01-2.5, 0.01-7, 0.01-8, 0.01-5, 0.01-1.5, 0.01-1 and 14-18 per cent. The electrode deposits C 1.7, W12, Ni 20, Cr 25, Co 41 per cent alloy on the work, to regenerate it after corrosion or abrasive wear. @(1pp)
