Experimental Verification of FEM Simulation of GMAW Welding
Original language description
The research focuses on verification of FEM simulation with experimental GMAW welds. In program Visual Environment simple FEM simulation of GMAW welding on Al alloy EN AW 7022 was created and these simulation data were compared with measured experimentaldata. To create good FEM model setting of heat source and material parameters are of great importance. To set parameters of heat source measurement of welding parameters, metallographic cut, weld bead and crater was experimentally done. During experiment, temperature was measured by several thermocouples and measured temperature was compared with simulation data. The difference of measured and simulated data was at maximum only 10°C and we can conclude that this result is very good. Simulations that obtain results close to reality are very useful for designing welded constructions. Designing from using precipitation hardenable Al alloys, e.g. series 7xxx, materials prone to softening, when welded, can be thus made easier and safer usin
