In this study, by using moving heat source and the temperature-dependent thermo-physical and mechanical properties of the base metal (SM490A) and weld metal (YGT50), we calculated the welding
FLOW-3D WELD Laser Welding CFD Software Welding FLOW-3D WELD provides powerful insights into laser welding processes to achieve process optimization. With better process control it is possible to minimize porosity, heat affected zones and control microstructure evolution. To accurately simulate laser welding processes, FLOW-3D WELD implements all the relevant physics such as laser heat sources, laser-material interaction, fluid flow,
In this study, the fatigue characteristics of SM490A, a material used in railway vehicles, were evaluated for welding and repair welding. Welding specimens and repair welding specimens were prepared and fatigue tests were conducted. In addition, finite element analysis (FEA) was conducted to evaluate the residual stress change.

Influence of Accelerated Cooling Condition on Welding Jul 14, 2015 · Electro-slag welding (ESW) has been widely used to join the box column because of high productivity. The heat input of ESW is far larger than those of other fusion welding processes, so ESW usually results in a long holding time over certain elevated temperature (t H time), a long cooling time from 800 to 500 °C (t 8/5 time), and a wide heat-affected zone (HAZ).
