Welding Simulation Of Tubular Joint Of HSLA S460 Using Simufact Welding Software

Abstract

Distortion is a major problem in welding fabrication, which is needed to be minimized and controlled in order to reduce the manufacturing cost due to distortion repair. This research studies about distortion behaviour due to Gas Metal Arc Welding (GMAW) robotic, process by simulation method using finite element software Simufact Welding. This simulation software is able to provide fast, reliable result of distortion and other derformations of the welded specimen. The material used in this research is High Strength Low Alloy (HSLA) S460. The modelling of the geometry is performed by using Catia VR20. Then, the geometries were imported to MSC Nastran Patran software for ‗Mesh‘. The geometry from MSC Nastran Patran then imported to Simufact Welding to undergo pre and post processing processes. The aim of the study is to understand the basic principles of welding simulation using Simufact Welding and to obtain the result of deformation on the tubular after the welding process. The results of T and K tubular then will be compared to the experimental result to validate the simulation result in the future. Other than understanding principle of welding process, this study also focuses on accommodating manual on building simulation models as educational purposes as future references.
