Dynamic control of current and voltage waveforms and droplet transfer for ultrasonic-wave-assisted underwater wet welding

Materials & Design, 2019
Ultrasonic vibration can change the dynamic behavior of the bubble and improve the process stability in underwater wet welding (UWW); thus, it has been attempted to profitably control metal transfer process.

The Effect of Flux Core Arc Welding (FCAW) Processes On Different Parameters

Procedia Engineering, 2012
AbstractFlux Core Arc Welding (FCAW) is an arc welding process that using continuous flux-cored filler wire. The flux is used as a welding protection from the atmosphere environment. This project is study about the effect of FCAW process on different parameters by using robotic welding with the variables in welding current, speed and arc voltage.

Effects of Welding Heat Input on Microstructure and Electrochemical Behavior of Flux‐Cored Arc‐Welded Q690 HSLA Steel

Advances in Materials Science and Engineering, Volume 2018, Issue 1, 2018., 2018
In this work, the weld metal (WM) for the Q690 high‐strength low‐alloy (HSLA) steel was prepared through flux‐cored arc welding (FCAW) at 10 kJ/cm and 20 kJ/cm heat inputs. The effect of welding heat input on the relationship between the microstructural factors and the electrochemical behavior of the FCAW Q690 steel was studied.

The Effect of Welding‐Pass Grouping on the Prediction Accuracy of Residual Stress in Multipass Butt Welding

Mathematical Problems in Engineering, Volume 2017, Issue 1, 2017., 2017
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.

Assessing the Very High Cycle Fatigue Behavior and Frequency Effect of Structural Steel Welds

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 4, Page 1529-1541, April 2025.
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.

Metallurgical characteristics of armour steel welded joints used for combat vehicle construction

Defence Technology, 2018
Austenitic stainless steel (ASS) and High nickel steel (HNS) welding consumables are being used for welding Q&T steels, as they have higher solubility for hydrogen in austenitic phase, to avoid hydrogen induced cracking (HIC) but they are very expensive.
