Optimization of a Welding Procedure for Making Critical Aluminum Welds on the LBNF Absorber Core Block [PDF]
JACoW IPAC2024 (2024) TUPS43The LBNF Absorber consists of thirteen 6061-T6 aluminum core blocks. The core blocks are water cooled with de-ionized (DI) water which becomes radioactive during beam operations. The cooling water flows through gun-drilled channels in the core blocks.

Solidification of Tungsten Inert Gas–Welded Austenitic Stainless Steel with 0.17 wt% N
steel research international, EarlyView.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.

A Multi-Sensor Interface to Improve the Learning Experience in Arc Welding Training Tasks [PDF]
arXiv, 2021 This paper presents the development of a multi-sensor user interface to facilitate the instruction of arc welding tasks. Traditional methods to acquire hand-eye coordination skills are typically conducted through one-to-one instruction where trainees must wear protective helmets and conduct several tests.
