On the use of linear-elastic local stresses to design load-carrying fillet-welded steel joints against static loading [PDF]
This paper uses local linear-elastic stresses to estimate the static strength of steel arc welded joints. The proposed design methodology was developed by taking as a starting point the fundamental concepts on which the Theory of Critical Distances (TCD)

The residual stress analysis of a thick welded structure requires a lot of time and computer memory, which are different from those in thin welded structure analysis. This study investigated the effect of residual stress due to welding‐pass grouping as a way to reduce the analysis time in multipass thick butt welding joint.

This study investigates the influence of laser power and welding speed on the quality of 304L stainless steel laser welds using numerical and experimental approaches. Results indicate that optimal parameters (4 kW, 3 m/min) enhance penetration while minimizing the heat‐affected zone, providing insights for industrial laser welding optimization ...

The Influence of Preheat on Distortion and Fatigue Crack Propagation Rate of FCAW Weld in A 36 Steel Structure [PDF]
Welding is one of the joining processes and it has been widely used, especially for steel welded structure in off-shore, pipeline or ship construction. Advantages of the welding joint are inexpensive, process joining can be done quickly and can produce ...

Assessing the Very High Cycle Fatigue Behavior and Frequency Effect of Structural Steel Welds
ABSTRACT The very high cycle fatigue behavior of S275J2+N flux‐core arc welded joints was investigated using the ultrasonic fatigue testing method at a loading frequency of 20 kHz. A bespoke specimen design featuring the weld toe was employed to more suitably represent in‐service welded joints than typical ultrasonic fatigue testing specimens.
