Malleable cast iron is cast iron that has excellent forging properties. Malleable cast iron is the result of heat treatment of white cast iron, so that cementite is decomposed to form graphite in the form of rosettes. Making malleable cast iron has ductility properties and is able to forge excellently, so it is often used for tooling and on railway components. Testing to determine the fatigue l…
in modern times like today, humans are increasingly spoiled with various tools that make work easeir. However, this iron based equipment often corrodes, resulting in losses both in terms of user safety and econimic value. Corrosion itself cannot be stopped but the corrosion rate can be inhibited by various techniques, one of which is the quenching method. This study aims to determine the effect…
This research will use gray cast iron as a welding specimen using SMAW. Before being welded, the specimen was made of a single V seam. The electrode used was ENi-Cl. Cast iron is a mixture of iron and carbon. The carbon content is between 2.0-6.67%. The Dye Penetrant test showed that there were several defects in the welding results, namely porosity, spatter, and crack. The macro structure test…
In an industrial world that continues to grow rapidly as it is today, there is no denying the use of gray cast iron is very widely used because it is a very important material in the manufacture of several engine components including truck suspension components, lathes, gears. This study aims to analyze the effect of post weld heat treatment on the welding results of shielded metal arc welding.…
