EFFECT OF WELDING SEQUENCE AND LINE HEATING ON FATIGUE STRENGTH FOR WELDED STRUCTURES
EFFECT OF WELDING SEQUENCE AND LINE HEATING ON FATIGUE STRENGTH FOR WELDED STRUCTURESFatigue strength of sound welded joints is affected not only by stress concentration due to structural discontinuity and local shape of weld toe but also by residual stresses. It is known that welding sequence makes the change of welding residual stress distribution.

Sequencing and Welding of Molecular Single‐Crystal Optical Waveguides [PDF]
Advanced Functional Materials, 2020 AbstractMolecular crystals are promising anisotropic optical transducing media for next‐generation optoelectronic microdevices that will be capable of secure transduction of information and impervious to external electromagnetic interference. However, their full potential has not been explored yet due to their poor processability, low mechanical ...

Welding sequence effects on residual stress distribution in offshore wind monopile structures [PDF]
Fracture and Structural Integrity, 2016 Residual stresses are often inevitably introduced into the material during the fabrication processes, such as welding, and are known to have significant effects on the subsequent fatigue crack growth behavior of welded structures.
