Testing and documentation guideline for the suitability of thin steel sheets for joining - Part 3: Laser beam welding. 2nd edition April 2025 The test methods specified in this steel-iron test sheet (SEP) are used to determine the suitability of steel thin sheets in automotive engineering for the laser beam welding joining process. Sample preparation, test conditions, determination of quality limits, the test method itself (continuous and stitched lap joints), destructive and non-destructive tests and documentation of the results are described. Sample diagrams for the test and templates for analysing the results are included. Publication: April 2025 Title and description automatically translated using Deepl API

This Stahl-Eisen test specification (SEP) applies to the automated ultrasonic immersion testing of appropriately prepared rolled or forged samples of steel for long products. Described are agreements, personnel qualification, preparation of test specimens, the test equipment and its inspection, adjustment, sensitivity classes, test volume, test procedure, assessment and test report. An example assessment is included. Important change: Sensitivity setting shall be carried out no more with a reference block (calibration block), but with a sample of the test job.

The test methods specified in this Stahl-Eisen test specification (SEP) describe the procedure to determine the suitability of automotive steel sheets for joining via the process of projection welding. Exemplarically, a nut with segmented projections is welded to a thin steel sheet. Described are sample preparation, welding equipment and test conditions, determination of quality levels, the test procedure itself (visual testing, thread engagement, weld nut set-down, push-out and pull-out testing, torque testing, metallography), as well as documentation of results. Example diagrams are given for testing and example sheets for the evaluation of results.

Testing and documentation guideline for the joining suitability of thin steel sheets Part 1: General information, 2nd edition, November 2024 This first part of the SEP 1220 test sheet series contains the general requirements. It serves as a basis for uniform material characterisation and is intended to standardise the exchange of data between material manufacturers and users. It describes the characterisation of base materials, sampling locations and general test conditions, including recommendations for cyclic testing. The data format for the data exchange of the tests (data header) is explained in detail. Publication: August 2011 Title and description automatically translated using Deepl API
