Investigate of gas arc welding process parameters to structure distortion effect

In this study, butt, and corner welding of St37/St37 and Ck45/Ck45 materials is performed using gas metal arc welding. Different process parameters are used in experimental studies by means of two different material, two different thicknesses, and two different welding velocities. As a result of experimental studies, decreasing distortion values are determined with increasing material thicknesses, and increasing distortion values are obtained with increasing welding velocities. At the second stage of the study, numerical calculation of the process is performed. In this stage, welding process is simulated at computer enviorenment using experimental process parameters. Numerical calculations are performed using Simufact Welding software. Prediction results with finite element analysis are determined compatible with the experimental results.
