Penetration state recognition for tungsten inert gas welding via an alternating cusp-shaped magnetic field-assisted molten pool-oscillation

open access: yesJournal of Materials Research and Technology
To ensure optimal penetration in direct current (DC) argon tungsten arc welding, a method was proposed to recognize the molten pool penetration during molten pool oscillation under alternating cusp-shaped magnetic field (ACSMF). An arc discharge model is

Solidification of Tungsten Inert Gas–Welded Austenitic Stainless Steel with 0.17 wt% N

open access: yessteel research international, Volume 96, Issue 5, May 2025.
The classical Scheil model with fast diffusion of nitrogen is used to describe the solidification of the weld seam from austenitic CrMnNi–N steel. The microsegregation of the elements Ni, Cr, Mn, Mo, and N is calculated and compared with experimental findings. Further, the correlation between secondary dendrite arm spacing and cooling rate is made.
