The present work investigates the effect of filler metals and heat input on weld bead geometry and mechanical properties of alloy316 welded by using GTAW.ER309
Keyhole gas tungsten arc welding(K-TIG)of Q345 low alloy steel plates was simulated by using SYSWELD software.The temperature field of the K-TIG welding process
Based on the SYSWELD software, a 3D finite element simulation is performed to investigate the temperature field and residual stress in the repair weld process o
