Finite Element Simulation of Arc Welding

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Arc welding processes (SMAW, GMAW [MIG], GTAW [TIG], SAW, …) are of the highest economic importance due to their flexible application and relatively low equipment costs for both robotic and/ or manually controlled joining. Due to a high melting rate and a high gap-bridging ability these processes are found most notably, in steel plants, power stations and shipbuilding.

Enteknograte engineers simulate the Welding with innovative CAE and virtual prototyping available in the non-linear structural codes LS-DYNA, Ansys, Comsol, Simufact Welding and ABAQUS. We are experienced with FEA Welding simulation.

Enteknograte Engineers simulate any type of welding such as Arc Welding, laser Beam Welding, RSW, FSW and transfer the results of welding simulation for next simulation like NVH, Crash test, Tension, Compression, shear test and fatigue simulation.

Special Conditions that included in Finite Element (FEA) of Welding Simulation

Welding cause to The components, commonly made of steel(s), are temporarily heated to specific temperatures Distribution. Taking into account the rate of heating and cooling, the material properties of a component can be altered and improved. The presence of certain agents can lead to changes in the carbon or nitrogen content of the component. In all welding processes, there are several decisive and important factors: Time (heating and holding time), temperature, atmosphere, and quenching or cooling conditions. In principle, there are two kinds of welding effect as heat treatment processes on material points:

  • processes resulting in a thorough change of the microstructure such as annealing and hardening
  • processes that result in merely changing regions close to the surface of the component such as diffusion and coating processes, carburization, case hardening, nitrating, boriding
