摘要: Surface fusions were performed by the gas tungsten arc welding (GTAW) surfacing process on plate castings of spheroidal graphite cast iron with a travel speed from 200 to 800 mm/min. Their geometry and hardness measured. Calorimetric measurements net heat input for GTAW have been conducted. A stepwise regression method was used develop relationship between parameters those fusion geometry, microhardness, efficiency, melting efficiency obtained data set.
