Effects of heat input on the mechanical properties of butt-welded high and ultra-high strength steels
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 ...
Weldability of cold-formed high strength and ultra-high strength steels
Hollow sections and cold-formed steels have a key role in modern structures and machinery. In addition, to benefit from full potentials of cold-formed steels, it is usually required to weld them to other steel parts of ...
Mechanical properties and microstructural evaluation of the heat-affected zone in ultra-high strength steels
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 ...
