Experimental investigation of the influence of the HAZ on the strength of welded T‐joints made of HSS

Steel Construction, Volume 18, Issue 3, Page 209-222, September 2025.
Abstract The welding process introduces heat, which may cause softening in the heat‐affected zone (HAZ) of high‐strength steels (HSS). In welded components such as hollow section joints, this localised reduction in strength can reduce the load‐bearing capacity by promoting early failure of the joint and decreasing plastic design strength.

Low‐Cycle Fatigue Performance of Directed Energy Deposited and Conventionally Manufactured Hybrid Gas Tungsten Arc‐Welded Duplex Stainless Steel Joints

Advanced Engineering Materials, Volume 26, Issue 23, December 2024.
The present work reveals novel results on the mircrostructure evolution and in particular the structural integrity of gas tungsten arc‐welded joints of directed energy deposition arc and as‐rolled standard duplex stainless steels compared to counterparts of the nonwelded base material as well as similar weldments of as‐rolled sheets.

Cyber‐physical‐based welding systems: Components and implementation strategies

IET Cyber-Physical Systems: Theory &Applications, Volume 9, Issue 4, Page 293-312, December 2024.
Increasing manufacturing efficiency means making digitalisation feasible for all technologies, including welding, given today's challenges. It can be shown that the digital migration of specific sub‐domains (e.g. visual inspection of the weld seam during quality assurance) is significantly more challenging and unimaginable without artificial ...

Preventing columnar grains growth during hybrid wire arc additive manufacturing of austenitic stainless steel 316L

Engineering Reports, Volume 6, Issue 11, November 2024.
WAAM process produce a wall structure full of long and large columnar grains, which can be improved by applying hot forging process, proper buildup process, and correct forging force & temperature to prevent the growth of columnar grains and producing small and equiaxed grains instead.

Effect of Nitrogen‐Added Shielding Gas on Microstructure Evolution of Welded Joints by Gas Tungsten Arc Welding Process in Duplex Stainless Steel 2205

steel research international, Volume 95, Issue 5, May 2024.
A challenge in welding duplex stainless steels is to limit ferritization in the heat‐affected zone to ensure high corrosion resistance. The work describes the influence of nitrogen gas in the Ar–N2 shielding atmosphere during a gas tungsten arc welding process.

Optimization‐improved thermal–mechanical simulation of welding residual stresses in welded connections

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 9, Page 1275-1293, 1 May 2024.
Abstract This paper presents a novel computer‐aided computational framework to determine the optimum shape parameters in a welding heat source model using a coupled supervised Gaussian process regression (GPR) and genetic algorithm (GA) approach in estimating the welding residual stresses. The experimental X‐ray diffraction (XRD) approach validates the
