Abstract: In recent years, there has been increasing use of thin-walled structures with a plate thickness of 6–10 mm in the construction of cruise ships. As one of the important processes of cruise ship construction, hybrid laser-arc ...

Abstract: The ultrasonic spot welding (USW) is widely used in the joining of multilayer Cu or Al tabs in the lithium-ion battery. Due to the high-frequency vibration of the sonotrode and various deformation in each interface, the ...

Abstract: With the implementation of more stringent emissions standards, ultrahigh strength steel has been increasingly used in vehicle body to reduce the carbon emissions, but softening in the heat-affected zone is one of the most ...

Abstract: In this study, an experimental investigation was presented on the oxidation behaviors of bituminous coal for different inert gases (N2 and CO2) at different concentrations (oxygen concentration indexes 21%, 18.4%, 15.8%, ...

Abstract: Application of additively manufactured steels is unavoidably involved in the resistance spot welding with conventionally manufactured steels. However, the microstructural evolution of an additive manufactured steel at high ...

Abstract: This paper outlines an experimentally based design method for a compatible 3DOF shoulder exoskeleton with an adaptive center of rotation (CoR) by matching the mechanical CoR with the anatomical CoR to reduce human–machine ...

Abstract: Residual stress prediction and controlling is important for structural integrity assessment of weldments. In this work, finite element (FE) and experimental methods were integrated to study the influence of welding sequence ...

Abstract: In a ship assembly process, a large number of compliant parts are involved. The ratio of the part thickness to the length or the width is typically 0.001–0.012. Fixture design is a critical task in the ship assembly process ...

Abstract: Application of maraging steels via selective laser melting process in the automotive industry was unavoidably involved in the resistance spot welding with conventional steels. Due to the rapid cooling rate of welding ...

Abstract: One of the major challenges in spot welding of ultrathin gage steel (e.g., <0.6 mm) is the short cap life. Because of the elevated temperature developed at the electrode/sheet interface, the electrodes often require ...
