TL;DR: In this article, the microstructural characteristics and mechanical properties, including micro-hardness, tensile properties, three-point bending properties and Charpy impact toughness at different test temperatures of 8mm thick S960 high strength steel plates were investigated following their joining by multi-pass ultra-narrow gap laser welding (NGLW) and gas metal arc welding (GMAW) techniques.

TL;DR: In this article, a hybrid laser/arc welding (HLAW) process was used to join high strength steel plates by using a double Y-groove shape to reduce the width of the heat affected zone and softened area.

Journal ArticleDOI
TL;DR: In this article, an experimental set up was designed and realized in order to achieve the friction welding of plastically deformed steel bars, where parts having same and different diameters deformed plastically, but same material was welded with different process parameters.

TL;DR: The majority of automotive body shop welding consists of resistance spot welding (RSW) steel sheet due to its inherently low cost and high speed as mentioned in this paper, and with the introduction of aluminum, it is desirable to use aluminum instead of RSW.

TL;DR: In this paper, a localised heat source introduces liquid metal into the gap between the pieces of steel, which on solidification forms an integral joint and requires an understanding of metallurgy, heat and fluid flow in order to achieve a reliable joint.
Abstract: Bridges, ships and much of the infrastructure on which modern civilisation depends, rely on the ability to connect pieces of well-engineered and shaped steel by welding. A localised heat source introduces liquid metal into the gap between the pieces of steel, which on solidification forms an integral joint. The process is complex with phenomena embracing all states of matter that are ordinarily observable, to wit: plasma, gas, liquid and solid. It requires an understanding of many aspects of metallurgy, heat and fluid flow in order to achieve a reliable joint. There also exist processes that do not involve fusion but nevertheless fall within the remit of welding.
