To address these limitations, several strategies have been developed, including increasing laser power, applying various laser beam shaping techniques, and optimizing assist gas configurations. In the present study, the combined effect of dynamic beam shaping and a mixed assist gas composition (nitrogen containing a low concentration of oxygen) is investigated for the first time. The study examines how this combined approach influences both the maximum achievable cutting speed and the dross formation. The resulting performance is systematically compared with previously established techniques, including static-beam oxygen cutting, static-beam nitrogen cutting, static-beam mixed gas cutting, and dynamic-beam nitrogen cutting. Cutting experiments performed on 10 mm and 12 mm-thick mild steel demonstrate that the synergy of dynamic beam shaping and mixed assist gas enables the production of dross-free cut edges at higher cutting speeds than those achievable with conventional static-beam oxygen cutting. These findings indicate that the combined strategy not only mitigates common quality issues but also enhances process efficiency, offering a promising direction for high-performance laser cutting of thick steel plates.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"143 ","pages":"Pages 263-268"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148703667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have investigated laser cutting of lithium metal anodes using nanosecond (ns) and picosecond (ps) pulsed lasers, as well as continuous-wave (CW) laser sources. In this work, the laser cutting of pure lithium metal anodes is experimentally evaluated using two ultrashort-pulsed lasers operating with picosecond and femtosecond (fs) pulse durations with burst mode capability. The burst mode emission is investigated to assess the influence of temporal pulse control on the cutting process on the different process regimes. At intermediate speeds, intermittent cuts and humping are observed, whereas at low speeds, successful cuts are obtained. The results showed the importance of the correct regulation of the number of pulses in a single burst with the fixed average power to achieve complete and clean cuts.

Laser welding offers a promising alternative, but joining morphologically dissimilar thermoplastics is challenging. This study investigates the use of a dark masking agent to enhance joint mechanical performance by increasing laser energy absorption in low-power scenarios during laser transmission welding (LTW) of solid PP to PE foam. Overlap joints were produced using a 1070 nm fiber laser across a power range of 30–100 W and scanning speeds of 200–2400 mm/s. The application of a masking agent significantly broadened the process window and increased the maximum force per unit length to 1.39 ± 0.26 N/mm, compared to 0.95 ± 0.03 N/mm for unmasked samples. Enhanced absorption at the interface promoted deeper, more stable melt formation, enabling excellent joint mechanical performance in low-power scenarios.

This study combines experimental trials with melt pool simulation to investigate how near infrared beam-shaping strategies influence copper hairpin welding. Experiments were carried out using a near infrared fibre laser with controlled core and ring power splits. Adding a small outer-beam component, rather than using a fully core-focused beam, reduced porosity and improved weld robustness, with the 5% ring condition giving the clearest improvement over the 100% core baseline. A three-dimensional melt pool model developed in FLOW-3D reproduced the main weld bead dimensions with errors below 10% and matched the expected scaling behaviour observed in the literature. The work provides two contributions: the combined use of high-fidelity computational modelling with experimentally validated near infrared beam shaping, and new evidence on the sensitivity of weld quality to power distribution. Together, the modelling and experimental results establish a workflow that can reduce physical trial requirements and support the development of advanced absorption-enhanced and beam-shaped welding strategies for industrial copper hairpin manufacture.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"143 ","pages":"Pages 420-423"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148703976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
