Equivalent material properties of the heat-affected zone in welded cold-formed rectangular hollow section connections
(03 / 2023)
articleA welded connection consists of three main material zones, the base material (BM), the heat-affect zone (HAZ), and the weld metal (WM). The strength of HAZ depends on the BM grade and manufacturing process, electrode grade, ... -
Experimental investigation on the tensile behaviour of welded RHS high strength steel X-joints
(01.02.2023)
articleThe newest version of prEN 1993-1-8 (2022) prescribes a material factor (Cf) to reduce the design resistance of welded joints made of high strength steel (HSS) mostly due to the lack of available experiments, given the ... -
A method for determining the constitutive model of the heat-affected zone using digital image correlation
(01.08.2022)
articleThe heat-affected zone (HAZ) is an unmelted region of a welded joint that has changed in material properties because of high temperatures during the welding process. HAZ has a lower strength than the base (parent) material ...
