Cultivar and environment influence growth, interactions, and yield in bread wheat–pea intercropping

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Intercropping can enhance productivity, resilience, and stability of cropping systems; however, the effects of drought and rising temperatures on cultivar‐specific resilience and economic performance remain insufficiently quantified. This study evaluated the influence of cultivar selection on growth, productivity, competitive interactions, and

Effect of PWHT and Electrical Parameters on Austenitic Phase, Sigma Phase and Corrosion in Duplex Steels S32205

Engineering Reports, Volume 8, Issue 4, April 2026.
Welding power and post‐weld heat treatment (PWHT) at 850°C influence phase transformations in S32205 duplex stainless steel, promoting sigma phase formation and reducing corrosion resistance. PWHT at 850°C also replicates HAZ‐like microstructures in base metal, enabling improved characterization of weld joint properties.

Fatigue Lifetime Assessment of HFMI‐Treated Welded Joints According to the Peak Stress Method

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 790-819, March 2026.
ABSTRACT High‐frequency mechanical impact (HFMI) is an effective post‐weld treatment that enhances fatigue strength by inducing compressive residual stresses, localized strain hardening, and increasing weld toe radii. The peak stress method (PSM) was recently extended to evaluate the fatigue strength of HFMI‐treated steel joints under uniaxial loading ...

Effects of welding parameters on percentage dilution and mechanical properties in welded joints of ultra-high hardness armour steels [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy
This study investigates the effects of Gas Metal Arc Welding (GMAW) parameters—specifically welding speed and stickout— on the dilution and mechanical properties of welded joints composed of ultra-high hardness quenched and tempered (UHH-Q&T) armor steel

Buckling resistance and residual stresses of welded HSS box columns

Steel Construction, Volume 19, Issue 1, Page 37-49, February 2026.
Abstract Welded box columns made of high‐strength steels (HSS) are characterized by high buckling resistance and low self‐weight. The residual stresses introduced by the welding process are of particular importance. In the area of the weld seams, the cooling process creates residual tensile stresses that are in equilibrium with the compression stresses

A computational fluid dynamic analysis of the effect of weld nozzle geometry changes on shielding gas coverage during gas metal arc welding

, 2013
Three geometry changes to the inner bore of a welding nozzle and their effects on weld quality during gas metal arc welding (GMAW) were investigated through the use of computational fluid dynamic (CFD) models and experimental trials. It was shown that an

Role of Machine Learning and Big Data Analytics in Enhancing the Efficiency of Gas Metal Arc Welding Process

IET Collaborative Intelligent Manufacturing, Volume 8, Issue 1, January/December 2026.
This study applies machine learning and big data analytics to optimise Gas Metal Arc Welding (GMAW) parameters, achieving high predictive accuracy for weld strength, penetration, and width. The methodology overcomes experimental data limitations by aggregating literature datasets and comparing multiple supervised algorithms. While demonstrated on GMAW,

Arc-based sensing in narrow groove pipe welding [PDF]

, 2006
Big gains in productivity are found in tandem and dual tandem pipeline welding but require highly skilled operators who have to control the position of the torch very accurately for long periods. This leads to high demands on the skills and stamina of

Effect of Arc Behaviour and Metal Transfer Process on Aluminium Welds during Ultrasonic Frequency Pulsed GMAW

Crystals, 2022
In order to study the influence of a novel current waveform control method of ultrasonic-frequency pulse (UFP) on arc behaviour, metal transfer process and the welds formation, monitoring system and image processing algorithms were employed for ...
