Influence of Temperature Variance on the Mechanical Properties of a Welded Bearing Support Flange Under Transient Conditions Using Finite Element Approach

Abstract

During a welding process, the influence of temperature distribution plays an important role affecting the vulnerable regions of the welded component. This research aims at presenting data on similar cases where a detailed comparative evaluation provides necessary data for designing a component based on its structural behaviour due to induced temperature variance during the groove welding process using finite element approach. The finite element simulations render a real-world scenario of the groove welding process by integrating the concept of ‘Moving heat source’ under transient conditions in ANSYS. The numerical comparative study is achieved by simulating a thermal study of the welded components of different bearing support flange plate thickness and evaluating its structural behaviour under induced thermal loads. The numerical solutions obtained from these simulations provide necessary data which helps in identifying the feasible design approach to increase the life of a welded component under such temperature-dependent conditions.
