Dual-phase steel DP590 and carbon fibre reinforced polymer (CFRP) were successfully
joined by laser welding. Experiments and numerical simulations were performed to clarify …

Zinc-coated ultra-high-strength steel (UHSS) sheets are highly susceptible to liquid metal
embrittlement (LME) during resistance spot welding. However, systematic understanding on …

Based on mechanical tests, microstructure characterizations and finite element simulations,
the mechanical properties and failure mechanisms of resistance spot welds (RSWs) were …

A meso-scale modeling approach is used to relate the local microstructural strength and
fracture resistance to the macro-scale failure response of spot welds in hot-stamped ultra …

Small specimen test techniques (SSTTs), developed for scarce materials, industrial
products, in-service equipment, etc., could be challenging to obtain sufficient materials for …

Resistance spot welds (RSWs) of quench and partitioning (Q&P) steels exhibit poor
mechanical properties due to the brittleness of the nugget microstructure. To solve this …

In this study, we used experimental characterizations and finite element analysis (FEA)
techniques to investigate the effect that welding current exerts on the microstructural features …

In this work, the mechanical properties and failure behaviors of resistance spot welds
(RSWs) were investigated under lap-shear (LS) loads. Different types (B1500HS …

Abstract Laser welding of 1.2 GPa-class cold-rolled quenching and partitioning steel with
martensite+ retained austenite microstructure was performed at different heat inputs ranging …

The mechanical performance and failure characteristics of resistance spot welds from two
grades of third-generation advanced high strength steels (3G-AHSS), designated 3G-980 …
