Analysis of metal transfer in gas metal arc welding [PDF]

AIP Conference Proceedings, 2019
The objective of this research is to find the parameters in gas metal arc welding for the application of steel. The force and velocity with which the droplet falls in the weld pool during the welding process were analysed. The effects of different shielding gases used in the welding process were studied by varying the percentage of different shielding ...

Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

Materials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.
