The hot rolling of steel sheets is a highly energy-intensive process. There are technical and
operational issues associated with this process, and the causes of these issues can be …

The rapid spread of the use of high-density polyethylene (HDPE) pipes is due to the wide
variety of methods for connecting them. This study keeps pace with the developments of butt …

In this study, the impact of pseudo-random non-proportional bending-torsion fatigue
loadings proportion on the fatigue life and the fracture surface topography was analyzed …

Undercut, as a typical surface imperfection at the weld toe, significantly impacts the weld
fatigue life. Neither the ISO5817 standard for imperfection level definition nor the traditional …

The additional local stress concentration caused by undercut and misaligned defects could
lead to lower fatigue strength of welded joints. The paper aims to investigate the effects of …

The fiber laser butt welding of AISI 304L and Q235 low-carbon steel is performed in this
study. An integrated heat source combined with an asymmetric double-ellipsoidal heat …

D406A steel is commonly used to fabricate the shell of aerospace craft and therefore
rigorous requirements have been set for welding quality of the steel. Laser welding has low …

Abstract In the European Union (EU), steel structures adhere to design and fabrication
standards outlined in EN 1993 and EN 1090–2. The second sets technical requirements for …

The investigation was aimed at evaluating the metallurgical and mechanical properties of
high-speed fiber laser welded thick Q890 high strength low alloy (HSLA) steel with varying …

Laser welding on thin plates of high-strength steel is increasing in various industrial
applications. The mechanical behavior of welded joints depends on their local properties …
