Title

Analysis of Mechanical Properties for Welded Cast Iron

Abstract

Abstract- Gray cast iron is most common type of cast iron and it can be successfully welded if cooling rates controlled during welding and after welding. Poor weldability of gray cast iron is due to the presence of much more carbon and silicon than in steel; witch results in cast iron is less ductile hence weld is subjected to more metallurgical complications in both the weld metal and the heat-affected zone. During cooling the carbon is precipitated in the form of graphite flakes which are difficult to weld, the weld metal does not fuse to the graphite flakes. The welding was carried out with manual shielded metal arc welding and oxyacetylene welding, using nickel based filler metal and cast iron rod (RCI) respectively to join grey cast iron. Welding is carried with preheating and post weld heat treatment (PWHT). A preheating temperature at 3500C and post heating temperature 8500C for one hour which improves mechanical properties of welded piece. Micro hardness, tensile tests were studied to evaluate the quality of welded joints.

Key Words

Gray cast iron, welding, preheating, post welding heat treatment (PWHT), HAZ, hardness and tensile strength.
