Influence of welding speed on weld pool dynamics and welding quality in underwater wet FCAW

Journal of Manufacturing Processes, 2020
Abstract The effects of welding speed on the molten pool dynamics, the weld forming and the diffusible hydrogen content in deposited metal during underwater wet flux cored arc welding (FCAW) were studied. The molten pool was elongated with a higher solidification speed, as the welding speed was increased.

Control of the Properties of Welded Joints in Wet Underwater Welding

Advanced Materials Research, 2021
The aquatic environment will negatively affect the processes that occur during the formation of a welded joint and leads to a deterioration in its properties. The welding conditions do not allow the use of traditional methods to improve the quality of the weld metal - preheating or subsequent heat treatment.
