SORPAS® Welding Simulation

SORPAS® is a professional welding software specialized for welding simulations and more beneficially for Smart Welding Optimizations to help people in industry quickly solve welding problems and effectively improve production stability and weld quality consistency.

SORPAS® has intelligently integrated numerical modeling techniques (finite element modeling FEM/FEA) with deeply learned industrial welding expertise. This has made SORPAS® a powerful yet practical tool directly useful for industrial applications with many smart functions for simulations and optimizations of resistance welding and mechanical joining processes.

The core values of the SORPAS® software are in the following:

  • Understanding the real problems and challenges facing the industry
  • Deep-learning the welding reality and intelligence of welding experts
  • Providing new technology to support daily welding work in industry

SORPAS® can be easily learned and used by engineers in industry to quickly solve their welding and joining problems. No prior knowledge of numerical simulation is needed to learn and use the software.

SORPAS® is widely used by auto makers and steel producers worldwide.

Ensure before weldingTM

Most welding problems can be rooted in a lack of optimization in the design and planning before welding production.

Finding the Process Window of good parameters is the key to weld planning, process control, and production maintenance for the best weld quality.

Process Optimization and Excel Batch Planning are the most used functions of SORPAS to predict the process window for improving weld quality, increasing production stability, and reducing expulsion (splash, spatter).
