Process Optimization

< Problem >   To predict process window and expulsion limit for a specific weld task of given combination of sheets.

< Solution >   Automated optimization functions to predict process window with weld growth curve and weldability lobe.

< Software >  SORPAS 2D.welding.

With the SORPAS 2D.welding Enterprise Edition , several functions for automated simulations have been developed to support welding process parameter optimization. It is possible to run fully automated procedures to generate the weld growth curves and the weldability lobes

weld growth curve

This is a weld growth curve generated automatically with SORPAS® for spot welding of 1 mm mild steel sheets in the range of weld current from 2 kA to 15 kA. The software has automatically identified the working range with green color points indicating the good spot welds, the red color points indicating splashes and the black color points indicating no weld.

spot welding weldability lobe

This is a weldability lobe generated automatically with SORPAS® for spot welding of 1 mm mild steel sheets with two welding process parameters (weld current and time) referring to ISO 14327:2004. Three reference weld nugget diameters (minimum, maximum and nominal) are indicated. It is also possible to generate the weldability lobe with weld current and force.
