3D Case 4 – Peel Strength test of weld nugget

You have to test a lot of different parameters to find out if the formed nugget is acceptable for a certain application. Very often, welding engineers investigate the parameters related to the mechanical properties of the nugget.

In order for you to to measure the mechanical properties of the nugget, you can use different mechanical tests, such as peel strength test, tensile strength test, cross tension test, hardness measurements etc. These tests can help you to evaluate if the weld nugget has an acceptable strength for the application.

SORPAS® 3D.testing can help to evaluate the weld strength based on simulations with actual welding and joining conditions. SORPAS® 3D.testing has also integrated standard templates for workpieces which makes it easier for the you to set up the welding design.

In this tutorial you see how to make a welding simulation and how to make a Peel strength test of the welded workpieces.

This tutorial demonstrates how to build a model with one spot weld and test the weld strength of the nugget. Also, it shows how to add testing tools to the workpieces. To demonstrate this case simple, no change of materials and process parameter has been made, we use default settings.

The example provides an excellent overview of building a model and making weld strength testing. It demonstrates how to build a model, adding contact interface, and adding testing tools.
