Abstract

The purpose of this study was to find the heat flow that effect cladding parameter of Nickel based alloy deposited on the cast iron substrate. The main objective was to study the effect of variable factor which is current, voltage and travel speed on the clad dimension or bead clad geometry. The cladding process was conducted using metal inert gas (MIG) weld method. Background knowledge about metal deposition including form of materials, heat sources or heat input that carry the thermal energy to form the molten pool. The application in industry that relate to its cladding process is mostly on the heavy application for example create boiler steam using welding or cladding technique. This experimental method involved manipulating one variable (cladding parameter) to determine if changes in this variable cause changes in another variable (geometry dimension). This method relies on controlled methods and the manipulation of variables to test a hypothesis. Finally, the geometry dimension of cladding tungsten carbide nickel based alloy on the cast iron was generating using Smart Weld Software. In addition, Minitab 16.1 Software that implemented full factorial technique has been used in order to make sure the optimization of parameters while conducting this experimental research. This research had successfully analyzed the data collected from this experimental research. The effect of welding parameters such as current, voltage and travel speed is directly affected geometry dimension of cast iron cladding material. Finally, the suggestion to enhance the optimization of parameter in cladding process also had been discussed.
