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.

2D Case 1-3 – Automated weld planning

The right weld parameters can take a lot of time. Though, simulation can reduce this time significantly. SORPAS® provides an easy function to find the optimized weld parameters for your weld task.

This tutorial demonstrates how to use the automated weld planning function Weld Task Description (WTD) is used to give you the optimized weld parameteres.

The automated weld planning function predicts the optimal welding procedure specification including optimal weld current, weld force, weld time, and hold time, according to user defined Weld Task Description (WTD). This function helps to find the optimal welding conditions in cases where new design has been chosen but haven’t found a welding profile.

You can use the WTD function in several ways which are shown in this tutorial.

Case 1: 3 sheets combination, using default welding condition. This means all welding process parameter are set to zero and the simulation makes a full optimization of the weld force, current, and weld time based on standard settings.

Case 2: 3 Sheets combination, using specified welding parameters. The “Profile” function is used to specify a welding profile to further optimize the process parameters.

 Case 3: 3 Sheets combination, using preferred parameters condition. The welding profile from case 1 is used but now the weld force is restricted to the machine’s limit.
