Control of the diffusible hydrogen content in different steel phases through the targeted use of different welding consumables in underwater wet welding

Klett, Jan; Mattos, Isabel B.F.; Maier, Hans Jürgen; e Silva, Regis H.G.; Hassel, Thomas (Weinheim : Wiley-VCH, 2020)

Due to the rising number of offshore structures all over the world, underwater wet welding has become increasingly relevant, mainly as a repair method. Welding in direct contact with water involves numerous challenges. A ...
Effect of the water depth on the hydrogen content in SMAW wet welded joints

Klett, Jan; Hecht-Linowitzki, Vitali; Grünzel, Oliver; Schmidt, Emily; Maier, Hans Jürgen; Hassel, Thomas ([Cham] : Springer International Publishing, 2020)

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 content is investigated for the case of ...
The applicability of the standard DIN EN ISO 3690 for the analysis of diffusible hydrogen content in underwater wet welding

Klett, Jan; Wolf, Thomas; Maier, Hans Jürgen; Hassel, Thomas (Basel : MDPI AG, 2020)

The European standard ISO 3690 regulates the measurement of diffusible hydrogen in arc-welded metal. It was designed for different welding methods performed in dry atmosphere (20% humidity). Some details of the standard ...
