Influence of the plate dimensions of a fillet weld joint on angular deformation and residual stresses

T-joints are essential structural components in applications such as shipbuilding, where optimised designs are crucial for ensuring load transmission and structural stability. This type of joint exhibits imperfections due to non-uniform heating and cooling behaviour during welding. This study analyses the influence of plate dimensions on the deformations and residual stresses induced by welding on the fillet weld joints. A literature review is conducted to understand the relationship between plate dimensions, angular deformation, and residual stresses, and is followed by a validation study to confirm the simulation methodology. Following this, different models with varying flange widths, plate thicknesses, and web heights are developed using the commercial software MSC PATRAN, and simulations are carried out with the commercial software SIMUFACT WELDING to model the process of gas metal arc welding, using the finite element method. The results confirm the influence of the plate dimensions, revealing that specimens with lower web heights exhibit increased deformation of 15% compared to the average. It is also found that whether the relationship is squared between the web height and flange width, less angular deformation on the flange will occur. For the plate dimensions and welding conditions considered here, it is found that a thicker flange plate (9 mm) produces greater welding angular deformations than a thinner one (6 mm). This is because depending on the heat input, thinner plates may exhibit less angular deformation than thicker ones when the same amount of heat is applied.
