Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects

Strain, Volume 61, Issue 2, April 2025.
ABSTRACT There are limited data on the very high‐cycle fatigue for structural steel welds for over 10 million cycles. The purpose of this research is a fatigue performance comparison of the welds made of steels S355JR+AR and S275JR+AR. The goal of reaching the gigacycle fatigue domain is achieved using the ultrasonic fatigue testing at 20 kHz.

Application possibility of arc welding processes for long butt joint of 75Mn steel plates without preheating

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
An arc welding process for long butt joint of high carbon −75Mn steel plates without preheating was selected, assuring quality of weld and productivity. Abstract In order to ensure the stability of the track mechanical device, this paper solves the problem of attaching the lock flange to the side of the rail.

Joining Optimization, Temperature, and IMC Evaluation for AL to Steel Friction Stir Spot Welding

Material Design &Processing Communication, Volume 2025, Issue 1, 2025.
Friction stir spot welding (FSSW) effectively solves many problematic welding metals, such as dissimilar metals and thin alloy sheets. Carbon steel‐AISI 1006 top sheet and an aluminum alloy AA2024‐T3 bottom sheet were joined by FSSW with a cylindrical pinless tool. Joints are evaluated in terms of temperature, mechanical characteristics, microstructure,

Microstructural Changes, Tensile, and Hardness Behaviour of Welded Ti‐6Al‐4V Plates

Material Design &Processing Communication, Volume 2024, Issue 1, 2024.
In this work, Ti‐6Al‐4V alloy was joined by tungsten inert gas (TIG) welding and the plates were undergone through optical microscopy test, elemental study, tensile test, hardness test, and fractographic observation. Plate‐A, with low value of current input, possesses α + β bimodal structure at BM, acicular martensite at HAZ, and Widmanstätten ...
