SORPAS 3D.testing

SORPAS® 3D.testing is a tool for weld strength testing. The key applications of SORPAS 3D.testing are the following:

  • To evaluate the weld and joint strengths based on simulations with actual welding and joining conditions.
  • To provide the weld and joint strengths dependent on actual materials and welding conditions to the subsequent structural and crash simulations.

A common method to evaluate the weld joint quality is by destructive testing to obtain the maximum breaking force in various loading modes and to obtain the failure modes (plug or interfacial failure).

SORPAS3D.testing can combine simulation of resistance welding process with weld strength tests:

  • Tensile shear test
  • Cross tension test
  • Axial tensile test
  • Peel (or bending) test
  • Torsion test

CAE/CAD engineers doing crash simulations need to implement weld joints with realistic weld strengths depending on actual materials and welding production processes. SORPAS3D.testing can output weld strength results to crash simulation models.
