Study on AI-based approaches to replace costly heat-treatment process for obtaining enhanced mechanical properties of the weld
摘要
Post-weld heat treatment (PWHT), a thermal processing technique, is generally used to improve metallurgical and mechanical properties of the weld. However, this process is time-consuming and resource-intensive, resulting in costlier end-products. The objective of this study is to substitute PWHT with an approach aided by Artificial Intelligence (AI) tools to make welding economical. Bonobo Optimizer (BO), an intelligent optimization tool, could outperform Particle Swarm Optimizer (PSO) to serve this purpose, as it showed a better convergence rate. The governing parameters of BO were configured to be adaptive; consequently, it became an intelligent optimization tool. BO could closely predict the input (process) parameters of welding that could give rise to the mechanical properties of the weld, namely yield strength, ultimate tensile strength, and elongation that could have been yielded through the PWHT. Thus, the novelty of this study deals with testing the applicability of AI tools to suggest the appropriate input/process parameters so that the enhanced properties of the weld could be achieved even by not adopting the costly process of PWHT.
