Abstract

The objective of this investigation is to determine the micro-structural behavior of a joint between cast iron and carbon steel by depositing a nickel-based substrate in the carbon steel. The filler was added through Shielded Metal Arc Welding using Castec 3099 (UTP 8) electrodes while the base materials were joined through Gas Tungsten Arc Welding with ER 70S – A1 bare electrodes. The Schaeffler diagram was used to analyze the chemical composition of the resulting weld beads. The results of the analysis performed on the welded area and the heat influence zone indicated the formation of acicular structures near the welded line when Castec 3099 electrodes are used and the formation of skeletal ferrite on the heat influence zone during the application of this welding process. An austenitic mixture is formed when ER 70S – A1 electrodes are used.
