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.","lang":"eng"}],"publication":"Journal of Manufacturing Processes","language":[{"iso":"eng"}],"ddc":["620"],"year":"2026","issue":"Special issue entitled: ‘Trends on spot joining’ published in Journal of Manufacturing Processes.","quality_controlled":"1","title":"Process window expansion with transferable applicability in three-layer dissimilar steel resistance spot welding via expulsion prevention","date_created":"2025-12-22T08:20:34Z","publisher":"Elsevier BV","status":"public","type":"journal_article","file_date_updated":"2025-12-22T08:21:51Z","article_type":"original","user_id":"65085","department":[{"_id":"157"}],"_id":"63391","citation":{"mla":"Yang, Keke, et al. “Process Window Expansion with Transferable Applicability in Three-Layer Dissimilar Steel Resistance Spot Welding via Expulsion Prevention.” <i>Journal of Manufacturing Processes</i>, vol. 157, no.

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."}],"publication":"Journal of Manufacturing Processes"},{"doi":"10.1016/j.jmapro.2025.10.027","title":"Single-step self-punching lockbolt process and equipment development for pre-hole-free joining of aluminum sheets using a dual-die system","volume":155,"date_created":"2025-10-28T09:53:07Z","author":[{"first_name":"Yannic","last_name":"Böhm","id":"84119","full_name":"Böhm, Yannic"},{"full_name":"Kappe, Fabian","id":"66459","last_name":"Kappe","first_name":"Fabian"},{"last_name":"Han","full_name":"Han, Daxin","id":"36544","first_name":"Daxin"},{"full_name":"Nordmann, Elmar","last_name":"Nordmann","first_name":"Elmar"},{"first_name":"Keke","last_name":"Yang","orcid":"0000-0001-9201-9304","full_name":"Yang, Keke","id":"65085"},{"last_name":"Jendrny","full_name":"Jendrny, Jörg","first_name":"Jörg"},{"full_name":"Gorr, Eugen","last_name":"Gorr","first_name":"Eugen"},{"full_name":"Meschut, Gerson","id":"32056","orcid":"0000-0002-2763-1246","last_name":"Meschut","first_name":"Gerson"}],"publisher":"Elsevier BV","date_updated":"2026-02-23T10:29:51Z","intvolume":"       155","page":"171-184","citation":{"ieee":"Y.

Eine zuverlässige Signal- und Leistungsübertragung erfor-dert minimale Übergangswiderstände an den elektrischen Anschlusspunkten des Massebolzensystems und muss ver-schiedenen Betriebs- und Umweltbedingungen über die gesamte Lebensdauer standhalten. Der Übergangswiderstand wird von mehreren Faktoren beeinflusst (z. B. Verbindungsgeometrie, Kontaktkraft, Temperatur, Werkstoff) und erhöht sich im Laufe der Betriebszeit infolge unterschiedlicher Alterungsmechanismen. Dieser Beitrag befasst sich mit der elektrischen Charakterisierung von Massebolzen aus AlMg5 mit einer ZnNi-beschichteten Stahl-Hutmutter auf einem AlMg3-Blech. Es werden ausgewählte fertigungs-, montage- und betriebsbedingte Einflussgrößen auf den elektrischen Verbindungs-widerstand analysiert. Als wirtschaftliche und etablierte Fügetechnologie kommt das Lichtbogenbolzenschweißen mit Hubzündung zum Einsatz. Zur Herstellung qualitativ hochwertiger Schweißverbindungen wird mittels einer statistischen Versuchsplanung ein geeigneter Referenzparametersatz ermittelt.

Liquid Metal Embrittlement (LME) cracking is a well-documented issue encountered during resistance spot welding (RSW) of zinc-coated advanced high-strength steels (AHSS) in automotive manufacturing. Given that existing research has predominantly focused on laboratory-scale samples and lacks investigation into the load-bearing capacity of joints under crash conditions, this study aims to fill these gaps by analyzing third-generation zinc-coated AHSS. S-Rail components were produced through stamping to replicate real-world manufacturing conditions and geometries of automotive parts. To account for the disturbances typically encountered in production, samples with LME cracks were intentionally fabricated. Subsequently, a modified three-point bending test, assisted by numerical simulations, was developed to effectively apply loads to the weld spots of the S-Rail components. Results from crash tests demonstrated that observed light crack severity does not significantly compromise the joint's load-bearing capacity or lead to earlier joint failure.</jats:p>","lang":"eng"}],"license":"https://creativecommons.org/licenses/by-nc/3.0/","file":[{"date_created":"2025-03-25T08:02:30Z","creator":"kekeyang","date_updated":"2025-03-25T08:02:30Z","file_name":"Shemat.pdf","file_id":"59092","access_level":"closed","file_size":1901767,"content_type":"application/pdf","relation":"main_file","success":1}],"ddc":["600"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2025","publisher":"Materials Research Forum LLC","date_created":"2025-03-25T07:59:49Z","title":"Influence of Liquid metal embrittlement on load-bearing capacity of resistance spot welds under crash loads: A study based on S-Rail components","type":"conference","status":"public","_id":"59091","department":[{"_id":"157"}],"user_id":"65085","file_date_updated":"2025-03-25T08:02:30Z","has_accepted_license":"1","publication_identifier":{"issn":["2474-395X"]},"publication_status":"published","intvolume":"        52","citation":{"ama":"Yang K, Biegler M, Happe L, et al.

In the field of online condition monitoring, non-destructive testing methods using active acoustic testing [1] emerged as innovative tools. These techniques are particularly effective because damage in joined structures leads to significant changes in their vibrational characteristics. However, the consistent use of online condition monitoring through active acoustic testing combined with complex pattern recognition for early crack detection in joined components has not yet been fully established. This research aims to develop an online crack detection system employing pattern recognition techniques under cyclic loading during fatigue tests, utilizing non-contact active acoustic testing with laser vibrometry. Due to the wide range of materials that can be joined, mechanical joining processes can be used in many different industry branches. Self-pierce riveting (SPR), in particular, is a well-established joining process. Therefore, the investigations for online crack detection initially focus on SPR joints. To achieve this, the fatigue behavior of SPR joints in a lap-shear configuration was characterized. Experimental fatigue testing demonstrated that SPR joint failure occurs either through cracks propagating in the sheet material away from the rivet or in the rivet foot, depending on the material combination. Laser vibrometry has been successfully used as a crack detection system and has proven to be effective in detecting crack initiation in SPR joints. Cracks can be detected without contact regardless of the material combination, the damage location, the size of the damage, or the type of damage.  The optimization of the crack detection system involved several key enhancements, including adjusting data acquisition to improve crack detection, incorporating principal component analysis (PCA) to reduce dimensionality, and implementing a classification model based on a global training dataset. An intuitive, problem-specific software demonstrator for analyzing the crack initiation behavior of SPR joints under cyclic loading was developed and iteratively optimized. Future work will focus on the implementation of an autoencoder network to further enhance crack detection capabilities.</jats:p>"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2474-395X"]},"publication_status":"published","intvolume":"        54","citation":{"chicago":"Olfert, Viktoria, Keke Yang, Maik Gollnick, Jacob Krause, David Hein, and Gerson Meschut. “Analysis of Fatigue Behaviour of Self-Piercing Riveted Joints under Cyclic Loading Using Laser Vibrometry.” In <i>Materials Research Proceedings</i>, Vol. 54.

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.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["Expulsion Resistance spot welding Finite element modelling Preheating Weldable current range Ultra-high strength steel"],"ddc":["670"]},{"publication_status":"published","quality_controlled":"1","publication_identifier":{"isbn":["978-3-96780-190-3"]},"citation":{"apa":"Yang, K., Seitz, G., Schreiber, V., Meschut, G., Biegler, M., Jüttner, S., &#38; Rethmeier, M.

The circuits in the onboard network are increasingly subject to greater demands regarding current-carrying capacity and long-term stability. Reliable signal and power transmission require minimal contact resistance at the electrical connection points of the ground stud system and must withstand various operating and environmental conditions over the entire service life. In this study, a ground stud made of AlMg5, with a ZnNi-coated steel cap nut was used on a 2.0 mm thick sheet of AlMg3. The electrical connection of the ground studs was made using tinned copper cable lugs and 35 mm² cables. To analyze the electrical resistance behavior in an accelerated test, the ground studs were subjected to a superimposed load with a cyclic current profile for 1008 hours under changing climatic conditions. The results show that under the chosen operational and environmental conditions, accelerated aging and intermittent resistance behavior occur. A characteristic drop in resistance during the test indicates the failure point of the electrical connection.
