Self-piercing riveting (SPR) has been widely used in automobile industry, and the strength prediction of SPR joints always attracts the attention of researchers. In this work, a prediction method of the cross-tension strength of SPR joints was proposed on the basis of finite element (FE) simulation and extreme gradient boosting decision tree (XGBoo...

The present paper deals with the numerical modeling and experimental testing of the clinched joint formed by DX51D + AZ150 and AISI 430 material pairs. The strength of the joint was determined experimentally by the tension and shear tests. The numerical model developed for the analysis was successfully validated with the experimental data. The stre...

The present investigation is focused on the development of a new FSW tool for polymer welding. The newly developed Self-Heated Friction Stir Welding (FSW) tool as well as a conventional FSW tool was employed to join 3-mm polypropylene sheets at different traverse speeds. The spindle torque and various forces exerted on the tool pin during welding w...

A more realistic approach is handpicked to scrutinize the weld strength of surface joints using tungsten inert gas welding for repair work. Due to the increased application of non-heat-treatable aluminum alloy (AA5182) in automobile structures, tensile weld strength is tested against heat-treatable filler (AA6061) at three age hardening temperature...

This paper investigates the effects of process parameters on the joint strength and process robustness when multi-layered joints of dissimilar metals are produced by ultrasonic metal welding (UMW). Three layers of 0.3-mm aluminium sheet are welded with a single 1.0-mm copper sheet which is representative of electric vehicle battery interconnects. A...

Lithium-ion-based secondary battery packs are emerging as an alternative power source and are being increasingly used in electric vehicles, hybrid or plug-in hybrid electric vehicles. Typically, a standard automotive battery pack consists of hundreds, even thousands, of individual cells which are connected in series and/or parallel to deliver the r...

The primary disadvantage of friction stir spot welding is the keyhole reminds after the welding process which removing of this keyhole is considered in this study. In addition, alumina nanopowder is incorporated into the weld stir zone as a technique to increase the joint strength. Flat friction stir spot welds with and without alumina nanopowder a...

Modified 9Cr-1Mo is a ferritic-martensitic steel widely used in steam generators of fast breeder reactors in the nuclear industry due to their enhanced creep resistance. In the present investigation, P91 steel was welded without preheat using three different heat inputs by pulsed short-circuit metal inert gas welding process using a ER90S-B9 wire e...

Thin zinc-coated steel sheets are brazed together using a copper-silicon filler alloy and employing a gas metal arc process with dynamic control of current and voltage transients. The actual heat inputs for different wire feed rates during brazing were estimated from the recorded current and voltage transients. Lowering of heat input was aimed at t...

Joining by plastic deformation, also called joining by forming techniques, has been developed as a powerful tool for joining a broad range of similar and dissimilar materials in an environmentally friendly manner. Generally, the joining by forming techniques fall into two distinctive categories, namely mechanical joining and solid state welding. In...
