Metallurgical characteristics of armour steel welded joints used for combat vehicle construction
Defence Technology, 2018 Austenitic stainless steel (ASS) and High nickel steel (HNS) welding consumables are being used for welding Q&T steels, as they have higher solubility for hydrogen in austenitic phase, to avoid hydrogen induced cracking (HIC) but they are very expensive.

Discontinuity Detection in the Shield Metal Arc Welding Process [PDF]
Sensors, 2017 This work proposes a new methodology for the detection of discontinuities in the weld bead applied in Shielded Metal Arc Welding (SMAW) processes. The detection system is based on two sensors—a microphone and piezoelectric—that acquire acoustic emissions generated during the welding.
