Abstract

Welding cast iron is used in ships, bridges, pressure vessels, industrial machinery, automobile, rolling stock and many other fields. Problems associated with welding are common issues in these fields. A Study was conducted to investigate Weldability of grey cast iron, as grey cast iron contains graphite in flake form, carbon can readily be introduced into the weld pool, causing weld metal embrittlement and Grey cast iron welds are subject to the formation of porosity and the cold cracking susceptibility of welds. When we observed that gray cast iron is welded non uniform heating and cooling in weld metal and in base metal generates harder Heat Affected Zone (HAZ), cold crack susceptibility and residual stress in weldement. Different methods investigate experimentally to minimize above difficulties. Those methods for reducing the effects of above problems were, minimize base metal dilution, compensate for shrinkage stresses, and the use of low strength filler metals to reduce cracking without sacrificing overall joint strength. Main while the beast type of arc welding electrodes for welding of grey cast iron are nickel and nickel-iron types have been used with or without preheating and / or post weld heat treatment. At the same time Cast iron and steel electrodes must be used with high preheats (530°C) to prevent cracking and the formation of hard deposits. The other mechanisms to improve Weldability of gray cast iron are Pre heating and/or Post heating of the base metal was experimentally employed and investigated.
