High-resolution 3D weld toe stress analysis and ACPD method for weld toe fatigue crack initiation [PDF]

, 2019
Weld toe fatigue crack initiation is highly dependent on the local weld toe stress-concentrating geometry including any inherent flaws. These flaws are responsible for premature fatigue crack initiation (FCI) and must be minimised to maximise the fatigue

Research On Laser-Arc Hybrid Welding Of Ht780 Steel

Welding in the World, 2011
The use of thick steel components that can be joined by one-layer-one-pass laser welding or laser-arc hybrid welding has been increasing with the trend of reducing the plate thickness by using higher strength steels. This has enhanced the demand for laser-arc hybrid welding of HT780 steels in the bridge and industrial machinery applications.
