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.

P 1589 - Development of a methodical approach for spatter prevention in resistance spot welding through multi-parameter process analysis using artificial intelligence In order to produce resource-efficient and affordable mobility, lightweight construction concepts made of modern high-strength sheet steel materials play a significant role. Resistance spot welding (RSW) is a frequently used method for joining these materials. During RSW, the disturbance variables that occur under real conditions (e.g., component tolerances) can lead to the formation of weld expulsion even in ideally parameterized welding processes, thus endangering processing safety. Weld expulsion reduces the weld nugget size under the specified target minimum diameters. To fundamentally exclude a decrease in strength due to such insufficient weld spots, more weld spots are set than necessary, resulting in increased cost and production effort. Consequently, the objective of the research project is to research and develop a methodological approach to predict expulsion through AI-Models. Further, it is aimed to develop an approach to prevent expulsion during the resistance spot welding process. For this purpose, realistic causes of expulsion formation (including proximity to edges, gap formation) will first be clearly characterized by AI-supported multiparametric analysis of the process variable curves. Subsequently, information on possible expulsion occurrence will be derived, and an ideal time for current shutoff will be predicted. This will achieve a maximum still spatterfree weld spot diameter. The data sets required for training the AI will be generated in the course of comprehensive experimental RSW tests at LWF Paderborn and finite element simulations at Fraunhofer IPK. In addition, effects on the load-bearing capacity of the connection and electrode life, depending on the respective cause of expulsion, will be determined beyond the current state of the art. The results enable SMEs in the sheet metal processing industry to better utilize modern steel materials and thus gain competitive advantages. The objective of this research project was accomplished.
