3D-Fall 3 – Prüfung der Kreuzspannungsfestigkeit

A lot of different parameters has to be tested regarding if the formed nugget is acceptable for the certain application. Parameters welding engineers often investigates are the mechanical properties of the nugget. To measure the mechanical properties of the nugget, different mechanical tests are used such as tensile strength test, cross tension test, hardness measurements etc. These tests can help to evaluate the weld nugget has an acceptable strength for the certain application. With SORPAS 3D testing it can help to evaluate the weld strength based on simulations with actual welding and joining conditions. SORPAS 3D testing have also integrating standard templates for workpieces which makes it easier for the user to set up the welding design. In this following tutorial it will show how to make a welding simulation and how to make a Cross tension strength test on the welded workpieces.
This tutorial demonstrates how to build a model with one spot weld and test the weld strength of the nugget. It shows how to add testing tool to the workpiece. To demonstrate this case simple, no change of materials and process parameter is done, we use default settings.
The example provides an excellent overview of building a model and doing weld strength testing. It demonstrates how to build a model, adding contact interface and adding testing tools.
