Welding Optimization

CAST-DESIGNER optimizer can execute multi-criteria non-linear optimization based on DOE/GA/PSO as known in Artificial Intelligence.

  • Multiple Criteria Targets: All physical problems could be optimized, including the distortion, displacement, stress and strain, temperature etc. For example: Single or multiple targets of the simulation, what the design engineer is trying to achieve like to maximize the welding speed, minimize distortion or minimize residual stress and fix condition during the welding process.
  • Multiple Design or Process Variable: Design elements that are allowed to vary, could be the Parametric CAD geometries like part dimensions, weld bead dimension, or process parameters, like material properties, welding velocity, welding current and voltage or the fix force and release time.
  • Genetic Algorithm and PSO in CAST-DESIGNER WELD Optimizer checks the results of each optimization iteration like distortion and intelligently sets the new value for the design variables like weld velocity or welding sequence. Such iterations are continued until the targets are achieved.
  • Complex user formulas are supported without programming.

CAST-DESIGNER Optimization supports parallel automatic optimization, this is a breakthrough technology to reduce the lead time of optimization.
