Underwater welding offers a wide range of applications in a variety of disciplines. The notion
of underwater welding appeals to many in the naval construction industry since it effectively …

For the numerical simulation of underwater wet flux-cored arc welding, the most crucial issue
is to investigate the intense interactions between the underwater bubble, arc plasma, and …

The vision-based welding status recognition (WSR) provides a basis for online welding
quality control. Due to the severe arc and fume interference in the welding area and limited …

This paper presents examinations of the role of the bead sequence in underwater welding.
Two specimens of wet welded layers made by covered electrodes with the use of …

In this study, the phenomenon of gas removal behaviors in the melt pool and the flow
behaviors of melt pool were observed using an in-situ X-ray imaging method. Based on the …

Local dry underwater wire arc additive manufacturing process (LDU-WAAM) was
innovatively proposed to repair the damaged large underwater structures. A thorough …

Automated industrial welding processes depend on a large number of factors interacting
with high complexity resulting in some sporadic and random variability of the manufactured …

The key mechanisms and process features of the inner physical processes and quality
improvement for the novel underwater submerged arc welding (USAW) were revealed with …

Grade AH36 ship steel plate, frequently used in offshore applications, was joined
underwater by shielded metal arc welding (SMAW) using two different types of electrodes …

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 …
