ABSTRACT

The Shielded Metal Arc Welding (SMAW) is most widely used welding process in the small scale industries because of its low cost, flexibility, portability and versatility. The project involves modeling of Shielded Metal Arc Welding of mild steel with the focus on 3- D Finite element analysis to predict the effect of SMAW (Shielded Metal Arc Welding) process parameters on temperature distribution and residual stresses in the model. A welding model will be created using a student edition MSC MARC software package with the capabilities to model welding processes. The welding model will be systematically developed from a 2-D into a 3-D model by using Creo parametric design software after that the model was inported in Patran software (which was also a Student Edition) for next process such as meshing of the model and defining properties of the model. Literature Review based welding heat input parameters will be applied in the model, temperature dependent material properties and actual structural restraints from the experimental will be modelled. Displacement and temperature distributions will be measured on the mild steel plates welded with the Shielded Metal Arc Welding process. This Project is totally simulation based modelling. A welding model will be created using the Student Edition MSC MARC software by testing different parameters on temperature distribution and residual stresses. Testing the various mechanical and thermal properties of material i.e. mild steel by using the software and calculating the residual stresses generated by Shielded Metal Arc Welding.
