We present the flexible delivery of picosecond laser pulses with up to 20 W average power over a 3-m-long sample anti-resonant hollow-core fiber (AR-HCF) for micromachining applications. Our experiments highlight importance optical mode purity AR-HCF manufacturing precision. demonstrate that compared an capillary core (d/D) ratio ~0.5, d/D ~0.68 exhibits better capability high-order-mode suppression, giving rise improved quality. Moreover, system pointing stability and set-up flexibility...
In the present study, feasibility of joining PA6-matrix thermoplastic composite panel and aluminum alloy is considered. Self-piercing riveting processes PA6 panels, panels with reinforcing fibers (glass fiber carbon fiber), 5754 sheets are systematically investigated. Macro characterizations appearance transverse sections self-piercing joints were conducted to provide more comprehensive understanding deformation during process. particular, effect on behaviors was characterized. Lap-shear...
Quenching and partitioning (Q&P) steels are among the most critical third-generation for realizing vehicle weight reduction improving safety performance. It is structure durability to have an excellent fatigue life of welds. In this study, Q&P1180 steel was laser spot welded (LSW) in order evaluate microhardness, mechanical properties, behavior its joints, which were compared with resistance welding (RSW). both types joining methods, zone composed lath martensite high microhardness value....
Abstract Medium-Mn transformation-induced plasticity steels have great potential to significantly reduce vehicle weight and improve fuel economy due their outstanding combination of high strength excellent ductility. One bottleneck the application is poor weldability resulting from Mn contents. In this paper, three resistance spot welding set-ups, including no shim, an interstitial-free steel shim at faying interface (shim-in) shims against electrodes (shim-out), were incorporated...
Al–Si coated 22MnB5 steels are one of the most important lightweight materials for automotive weight reduction and safety improvement due to its advantages light weight, high strength good formability at temperature. Considering formation α-ferrite caused by coating deteriorating weld mechanical performance, common way in industry is remove prior laser welding. In this work, a patented laser-filler wire welding process was developed with steel inhibit achieve quality without requirement...
