Abstract
One of the major causes of structural failure in service is attributed to failure in its parts, especially at the welded joints. Engineers and other users of low carbon steel tend to find solution to this problem by considering the application of Post weld heat treatment (TTP).The Microstructure and mechanical properties of heat-treated and untreated welded low carbon steel samples were determined. Simulation of the specimens was also generated using Autodesk Inventor Simulation CFD 2015 Application Software. The CFD model (simulation) showed clearly the visual style wireframe and shaded mesh (XY, and XZ planes and the temperature profiles for different passes), which is a veritable tool to evaluate residual stress that is likely to happen in real welding process. The results also revealed that better quality mechanical behaviour of welded low carbon steel is elicited by post-weld normalizing and annealing TTP.
