Effects of heat input on the mechanical properties of butt-welded high and ultra-high strength steels
(Elsevier, 2019-08-09)
In this study, the mechanical properties of butt-welded thin plates made of S700, S960 and S1100 steels under various heat inputs (HI) are investigated. The gas metal arc welding (GMAW) process with two different levels ...
Mechanical properties and microstructural evaluation of the heat-affected zone in ultra-high strength steels
(Elsevier, 2020-09-17)
This paper presents an investigation into the mechanical properties of ultra-high strength steels (UHSSs) (with nominal yield stress of 960 and 1100 MPa) after welding. Seven weld thermal cycles were simulated using a ...
Fatigue strength of longitudinal load-carrying welds in beams made of ultra-high-strength steel
(Elsevier, 2021-02-06)
The present study experimentally investigates the fatigue strength of longitudinally loaded welded joints in beam structures made of ultra-high-strength steel. Hereby, the effects of different manufacturing methods and ...
