As high-strength and ultra-high-strength steels are widely used in all kinds of modern welded constructions, a lot of research is carried out to investigate the mechanical properties of the weldments of these steels, but there is little information o

The need for welded structures of high-strength steels requires detailed studies on the factors influencing the behaviour of these steels during welding. The present work introduces results on the influence of the welding gap on the structure and som

Nowadays, the use of high strength (HS) and ultra-high strength steels (UHS) increases, notably in welded constructions. These steels are mainly exploited in heavy loaded welded constructions such as bridges, cranes and excavators, in pressure vessel
