Journal ArticleDOI
Critical review of automotive steels spot welding: process, structure and properties
TL;DR: In this article, the fundamental understanding of structure-properties relationship in automotive steels resistance spot welds is discussed. And a brief review of friction stir spot welding, as an alternative to RSW, is also included.
Journal ArticleDOI
The effect of intercritical heat treatment temperature on the tensile properties and work hardening behavior of ferrite–martensite dual phase steel sheets
TL;DR: In this paper, the authors investigated the tensile properties and work hardening behavior of dual phase (DP) steels with an equal amount of ferrite and martensite.
Journal ArticleDOI
Failure mode transition in AHSS resistance spot welds. Part I. Controlling factors
TL;DR: In this paper, the authors investigated and analyzed the transition between interfacial and pull-out failure modes in AHSS resistance spot welds during the tensile-shear test by the use of analytical approach.
Journal ArticleDOI
Key factors influencing mechanical performance of dual phase steel resistance spot welds
TL;DR: In this paper, the peak load of the spot welds is not proportionally correlated to the tensile strength of the base metal, and the strength/ductility of failure location is one of the main factors governing peak load and energy absorption of spot weld.
Journal ArticleDOI
Influence of fusion zone size and failure mode on mechanical performance of dissimilar resistance spot welds of AISI 1008 low carbon steel and DP600 advanced high strength steel
TL;DR: In this paper, the effect of welding parameters (welding time, welding current and electrode force) on the overload failure mode and mechanical performance of dissimilar resistance spot welds between drawing quality special killed AISI 1008 low carbon steel and DP600 dual phase steel was investigated.
