MECHANICAL, 2021 Underwater wet welding (UWW) is widely used in the repair of offshore construction and underwater pipelines using the Shielded Metal Arc Welding (SMAW) method. This research was conducted to see the effect of flow (0 m/s, 1 m/s, and 2 m/s) and water depth (2.5 m and 5 m) on the depth weld metal penetration of the SS400 steel underwater welded joints ...

Influence of welded depth and CuCl2 pretreated dowels on wood dowel welding [PDF]
Journal of Wood Science, 2017 This study examined the influence of welded depth and CuCl2 pretreated dowels on wood dowel welding. In untreated group without pretreatment (group A), test results indicated that welded depth 40 mm exhibited higher pullout resistance than the other welded depths.

Depth of penetration in gas metal arc welding [PDF]
Science and Technology of Welding and Joining, 1999 A model is presented of the depth of penetration in gas metal arc welding. This model is based on the assumption that the heat and mass transfer to the weld pool and the depth of penetration may be correlated by a dimensionless relation. This correlation leads to an analytical expression for depth of penetration, which involves empirical constants ...
