Cyber‐physical‐based welding systems: Components and implementation strategies

IET Cyber-Physical Systems: Theory &Applications, Volume 9, Issue 4, Page 293-312, December 2024.
Increasing manufacturing efficiency means making digitalisation feasible for all technologies, including welding, given today's challenges. It can be shown that the digital migration of specific sub‐domains (e.g. visual inspection of the weld seam during quality assurance) is significantly more challenging and unimaginable without artificial ...

Time resolved Thomson scattering diagnostic of pulsed gas metal arc welding (GMAW) process

Journal of Physics: Conference Series, 2014
In this work a Thomson scattering diagnostic technique was applied to obtain time resolved electron temperature and density values during a gas metal arc welding (GMAW) process. The investigated GMAW process was run with aluminum wire (AlMg 4,5 Mn) with 1.2 mm diameter as a wire electrode, argon as a shielding gas and peak currents in the range of 400 ...

Preventing columnar grains growth during hybrid wire arc additive manufacturing of austenitic stainless steel 316L

Engineering Reports, Volume 6, Issue 11, November 2024.
WAAM process produce a wall structure full of long and large columnar grains, which can be improved by applying hot forging process, proper buildup process, and correct forging force & temperature to prevent the growth of columnar grains and producing small and equiaxed grains instead.
