摘要：PURPOSE:To provide a titled build-up welding electrode which can form weld beads having extremely high hardness at high temp. and having excellent thermal impact resistance, etc. by contg. C, Si, B, Cr, Mn, Zn respectively at prescribed ratios and consisting of the balance Ni and unavoidable impurities. CONSTITUTION:A titled build-up welding electrode of an Ni alloy contg., by wt%, 0.03-1.80% C, 2.5-9.0% Si, 0.03-2.0% B, 736% Cr, 0.005-0.80% Mn, and 0.001-0.30% Zn and consisting of the balance Ni and unavoidable impurities. If such electrode is used, weld beads provided with the high temp. hardness, thermal impact resistance and vanadium attack resistance which the engine valves and valve seats of internal combustion engines, more particularly, high performance diesel engines reguire can be formed. this welding electrode does not contain Co which is a cause for an increase in cost and further in spite of its high content of Ni, the electrode is adaptable for oxy-acetylene build-up welding.
