Specifities of application of activating fluxes in electrical welding in protective atmosphere [PDF]
FME Transactions, 2020 Without the increase in welding current, activating fluxes for arc welding with a non-consumable electrode (ATIG) and for welding with a consumable electrode (AMIG) allow for the increase in depth of penetration 2-4 times.

Characterization of titanium welded joints by the orbital gas tungsten arc welding process for aerospace application [PDF]
, 2010 In this work, three welding programs for orbital gas tungsten arc welding (GTAW), previously developed, were used, using pulsed current and increasing speed (#A), constant current (#B) and pulsed current and decreasing current (#C).

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
