simulations of laser welding processes conducted using VisualWeld (SYSWELD) software …

Wet underwater welding has proved to be the most suitable solution for underwater repairs
and fabrication works. However, number of difficulties are faced that are specifically depicted …

The article presents a comparison of modern computational techniques used in numerical
analyses of welding processes. The principles of the “transient” technique calculations with …

In this paper, a comparison of the mechanical properties of high-strength low-alloy S460N
steel welded joints is presented. The welded joints were made by the gas metal arc welding …

Some marine and offshore structure elements exploited in the water cannot be brought to
the surface of the water as this will generate high costs, and for this reason, they require in …

In this paper the influence of in situ local heat treatment performed by additional stitches on
the weldability of high-strength low-alloy (HSLA) S355J2C+ N steel was tested. The …

In this paper the influence of tack welds distribution and welding sequence on angular
distortion of the Tungsten Inert Gas (TIG) welded joint was tested. Additionally, the effect of …

Hydrogen-induced cold cracking is a huge challenge in underwater wet welding. In the
present study, the influence of water depth on the diffusible and residually stored hydrogen …

Hydrogen-assisted cracking is a major challenge in underwater wet welding of high-strength
steels with a carbon equivalent larger than 0.4 wt%. In dry welding processes, post-weld …

The ultrasonic-frequency pulse underwater wet welding (UFP-UWW) process was achieved
through a constant-voltage-mode power source connecting an ultrasonic-frequency pulse …
