To overcome\r\nthermal imbalance constraints, an innovative strategy leveraging plastic shell containment is proposed to elevate\r\nthe expulsion-free heat input threshold. By applying a combined preheating and ramping current profile, a coordinated “shell-first, nugget-second” sequence is achieved. This mechanism creates a solid-state barrier prior to\r\nrapid fusion, effectively preventing expulsion. Experimental results demonstrate that while the reference\r\nconstant-current schedule fails to maintain a process window under a 2 mm initial gap (IG) disturbance, the\r\nproposed strategy significantly enhances process stability. It increases the maximum expulsion-free heat input by\r\n24 % (to 6338 J) under normal conditions and by 77 % (to 6482 J) under the IG condition. Crucially, the\r\nincreased heat input drives nugget growth across all interfaces, achieving a penetration depth of 0.38 mm (48 %\r\npenetration ratio) in the low-carbon steel sheet under the gap condition. These findings validate the strategy’s\r\neffectiveness in ensuring weld quality and robustness, which is further confirmed by its transferability to a lowerresistivity DX54D cover sheet."}],"date_created":"2025-12-22T08:20:34Z","publisher":"Elsevier BV","title":"Process window expansion with transferable applicability in three-layer dissimilar steel resistance spot welding via expulsion prevention","issue":"Special issue entitled: ‘Trends on spot joining’ published in Journal of Manufacturing Processes.","quality_controlled":"1","year":"2026"},{"title":"Predictive modeling of tolerance-dependent failure behavior of self-pierce riveted joints: From coupon-level tests to sub-component validation","date_created":"2025-12-26T13:41:43Z","publisher":"Elsevier BV","year":"2026","issue":"Special issue entitled: ‘Trends on spot joining’ published in Journal of Manufacturing Processes.","quality_controlled":"1","language":[{"iso":"eng"}],"ddc":["620"],"file":[{"file_size":28796238,"file_id":"63419","file_name":"1-s2.0-S1526612525013787-main.pdf","access_level":"closed","date_updated":"2025-12-26T13:42:22Z","creator":"kekeyang","date_created":"2025-12-26T13:42:22Z","success":1,"relation":"main_file","content_type":"application/pdf"}],"abstract":[{"text":"Manufacturing tolerances have a measurable influence on the structural integrity of self-piercing riveted (SPR) joints in automotive applications, yet their quantitative impact on load-bearing behavior remains insufficiently resolved. This study establishes a validated hierarchical methodology to predict tolerance-dependent failure behavior of SPR joints, progressing from coupon to sub-component scale through an integrated experimental–numerical approach. Five critical manufacturing tolerances, including rivet length (±0.5 mm), rivet head position (±0.3 mm), orthogonality deviation (2.8° and 5°), lateral offset (up to 1.2 mm), and flange overlap reduction (up to 7.5 mm), were investigated. Steel–steel joints exhibited a higher sensitivity to tolerances by a factor of 2–3 compared to steel–aluminum joints. A unified effective rivet length concept was developed to consolidate the geometric effects of all tolerances into a single physically meaningful parameter, enabling load-bearing capacity prediction with R2 > 0.95 across all evaluated loading directions. The sub-component validation employing T-joint specimens indicates a 2–3 fold amplification of tolerance effects at critical structural regions, providing experimental evidence for the hierarchical scaling principle. The methodology was implemented in a tolerance-dependent CONSTRAINED_SPR3 formulation, providing >99 % computational efficiency improvement while maintaining a deviation in maximum force prediction within ±7 %. This framework enables the physically consistent representation of manufacturing variation within large-scale simulations and establishes a transferable basis for tolerance-resilient virtual vehicle development.","lang":"eng"}],"publication":"Journal of Manufacturing Processes","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/S1526612525013787?via%3Dihub","open_access":"1"}],"doi":"10.1016/j.jmapro.2025.12.058","author":[{"first_name":"Viktoria","last_name":"Olfert","id":"5974","full_name":"Olfert, Viktoria"},{"id":"65085","full_name":"Yang, Keke","last_name":"Yang","orcid":"0000-0001-9201-9304","first_name":"Keke"},{"first_name":"Philip","full_name":"Rochel, Philip","last_name":"Rochel"},{"last_name":"Bähr","full_name":"Bähr, Philipp","first_name":"Philipp"},{"last_name":"Hein","id":"7728","full_name":"Hein, David","first_name":"David"},{"first_name":"Silke","full_name":"Sommer, Silke","last_name":"Sommer"},{"first_name":"Gerson","full_name":"Meschut, Gerson","id":"32056","last_name":"Meschut","orcid":"0000-0002-2763-1246"}],"volume":157,"oa":"1","date_updated":"2025-12-26T14:06:38Z","citation":{"chicago":"Olfert, Viktoria, Keke Yang, Philip Rochel, Philipp Bähr, David Hein, Silke Sommer, and Gerson Meschut. “Predictive Modeling of Tolerance-Dependent Failure Behavior of Self-Pierce Riveted Joints: From Coupon-Level Tests to Sub-Component Validation.” <i>Journal of Manufacturing Processes</i> 157, no.

This study presents a novel approach to prevent expulsion by employing a preheating current. Through characteristic analysis of joint formation under critical welding current, the importance of plastic material encapsulation around the weld nugget (plastic shell) at high temperatures in preventing expulsion is highlighted. To evaluate the effect of preheating on the plastic shell and understand its mechanism in expulsion prevention, a two-dimensional welding simulation model for dissimilar ultra-high strength steel joints was established. The results showed that optimal preheating enhances the thickness of the plastic shell, improving its ability to encapsulate the weld nugget during the primary welding phase, thereby diminishing expulsion risks. Experimental validation confirmed that by employing the optimal preheating current, the maximum nugget diameter was enhanced to 9.42 mm, marking an increase of 13.4 % and extending the weldable current range by 27.5 %. Under quasi-static cross-tensile loading, joints with preheating demonstrated a 7.9 % enhancement in maximum load-bearing capacity compared to joints without preheating, showing a reproducible and complete pull-out failure mode within the heat-affected zone. This study offers a prevention method based on underlying mechanisms, providing a new perspective for future research on welding parameter optimization with the aim of expulsion prevention."}],"publication":"Journal of Manufacturing Processes","title":"Expulsion prevention in resistance spot welding of dissimilar joints with ultra-high strength steel: An analysis of the mechanism and effect of preheating current","date_created":"2024-06-23T21:58:29Z","publisher":"Elsevier BV","year":"2024","quality_controlled":"1"},{"user_id":"66459","department":[{"_id":"157"},{"_id":"630"}],"project":[{"_id":"130","name":"TRR 285: TRR 285","grant_number":"418701707"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"name":"TRR 285 – C02: TRR 285 - Subproject C02","_id":"146"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"_id":"144","name":"TRR 285 – B05: TRR 285 - Subproject B05"}],"_id":"34244","language":[{"iso":"eng"}],"keyword":["Industrial and Manufacturing Engineering","Management Science and Operations Research","Strategy and Management"],"type":"journal_article","publication":"Journal of Manufacturing Processes","status":"public","date_created":"2022-12-06T13:57:46Z","author":[{"last_name":"Kappe","full_name":"Kappe, Fabian","first_name":"Fabian"},{"last_name":"Zirngibl","full_name":"Zirngibl, Christoph","first_name":"Christoph"},{"full_name":"Schleich, Benjamin","last_name":"Schleich","first_name":"Benjamin"},{"last_name":"Bobbert","full_name":"Bobbert, Mathias","first_name":"Mathias"},{"full_name":"Wartzack, Sandro","last_name":"Wartzack","first_name":"Sandro"},{"first_name":"Gerson","last_name":"Meschut","full_name":"Meschut, Gerson"}],"volume":84,"publisher":"Elsevier BV","date_updated":"2023-04-27T08:53:36Z","doi":"10.1016/j.jmapro.2022.11.019","title":"Determining the influence of different process parameters on the versatile self-piercing riveting process using numerical methods","publication_status":"published","publication_identifier":{"issn":["1526-6125"]},"quality_controlled":"1","citation":{"mla":"Kappe, Fabian, et al. “Determining the Influence of Different Process Parameters on the Versatile Self-Piercing Riveting Process Using Numerical Methods.” <i>Journal of Manufacturing Processes</i>, vol. 84, Elsevier BV, 2022, pp. 1438–48, doi:<a href=\"https://doi.org/10.1016/j.jmapro.2022.11.019\">10.1016/j.jmapro.2022.11.019</a>.","short":"F.
