Finite Element Welding Simulation with ESI SYSWELD (FEA/FEM)

Simulate a 2d mmaw lap-joint in SYSWELD using St52 with matching filler. Apply the Goldak model to predict weld pool heat gradients and perform thermo-metallurgical and phase evolution analyses.

Create a 2D MMAW geometry in the yx plane by defining nodes and meshing with bias, assign weld, base metal, and clamps, then extract 1D cooling and save.

Configure a 2d MMAW welding simulation in SYSWELD by defining the weld path, selecting base and filler metals, tuning the Goldak weld pool, and applying cooling, clamping, and thermo-metallurgical analysis.

Open the fdb file in the visual viewer for 2d mmaw results, inspect contour and temperature results, assess weld peak temperature and cooling, and review ferrite, bainite, and martensite transformations.

Perform a 3d manual metal arc welding simulation for 316l stainless steel, including thermo-metallurgical analysis and phase transformation from austenite to ferrite, with post-processing to export curves and videos.

Create a 3d mmaw welding geometry in visual mesh by sweeping a 2d mesh into 3d, shaping left, right, and weld parts with biasing and clamping for heat transfer.

Set up a 3d mmaw welding simulation in sysweld, define the welding trajectory and start and end nodes, assign 316l components with 316 filler, and generate the thermo-metallurgical input.

Explore 3d mmaw results and post-processing to analyze temperature node data, phase changes, and weld parameters in 316L stainless steel, with animated heat source, plots, and video export.

Learn residual stress theory in welding, its causes, effects, and mitigation—preheating, post weld heat treatment, and optimized welding sequences—through a 3D MMAW analysis and result post-processing.

Open the weld model, configure the residual stress analysis in the welding advisor, set mechanical inputs and clamping conditions, and run a multi-processor solve.

Analyze residual stress after welding by viewing post-2000 results, plotting transverse and longitudinal profiles (x x, y y) and von Mises values, and identifying high-stress zones via profile paths.

Learn a finite element welding simulation of resistance spot welding with thermal analysis. Explore the rw model, electrode caps, contact resistances, and parameters such as squeeze time and welding time.

In Visual Environment 15, this lecture shows creating a two-sheet spot weld mesh, applying ISO 5821 mappings, and setting cap size 16 and electrode details while adjusting the solver settings.

Save the model, configure spot weld parameters such as intensity, frequency, squeezing time, and duration, select material, and run thermal analysis to observe molten zone evolution and log results.

Analyze the welding simulation results, including the evolution and size of the molten zone, maximum temperature 1528, and the heat affected zone, with ferrite transforming to martensite.
