Strain Strengthening

In this paper, Finite Element Modeling (FEM) using Marc software was carried out to investigate the strain-strengthening effect on residual stress in 06Cr19Ni10 austenitic stainless steel weld joint made by MIG welding. The model prediction of residual stress was validated by X-ray Diffraction (XRD) method. It is found that there is a good agreement between the model predictions and the experimental results. The strain-strengthening can significantly improve the distribution of residual welding stress. Specifically in weld zone and the heat-affected zone (HAZ), residual stress decreases with increasing strain-strengthening level.

Materials Used

The welded joint always contains the microstrain when welding is complete. The microstrain generates distortion and changes of the physical shape of the weld joint. The purpose of the study was to observe the pattern and direction of residual stress before and after welding Q900&T125 and Q900&T175 Steel. The materials used for this study is Hot Rolled Plate Steel made by Indonesia steel industry. Method of this study is 1. Q900&T125 and Q900&T125 Steel machined in V-butt joint. This joints weld by using manual gas metal arc welding, Q900&T125 and Q900&T125 Steel weld joint can be found. 2. Measuring the distance from the lattice planes before and after welding by using Neutron-Ray Diffraction. Then the microstrain can be found. By involving Poisson numbers and modulus of elasticity of material in microstrain obtained residual stress. All the pattern of microstrain is compressive stress and leads to the weld center.
