田中 学

On February in 2008, Manabu Tanaka was a Professor at Joining and Welding Research Institute (JWRI), The University of Osaka, and since then, he has continued at The University of Osaka. His major interests are in the physics of welding and WAAM (Wire Arc Additive Manufacturing), including plasma diagnostics, electrode phenomena, and numerical modeling. Specifically, he conducted the laser scattering measurement of arc plasmas at atmospheric pressure, and then he made clear the physical state of the anode boundary layer in argon gas tungsten arc and also revealed the existence of departure from the local thermodynamic equilibrium (LTE) in the arc. Continuously, he showed the mechanism of deep penetration in gas tungsten arc welding with activating flux (A-TIG) by the plasma diagnostics together with a unified numerical simulation of gas tungsten arc welding process.
He is now interested in the following subjects for his researches in The University of Osaka;
1) Understanding of arc, metal transfer and weld pool, through “visualization” of the phenomena in welding and WAAM.
2) Mechanisms of welding and WAAM, with the aim of controlling and improving quality and productivity.
3) Development of digital twins utilizing validated numerical simulations for a new era manufacturing.
4) Innovation of welding and WAAM processes driven by the physics of arcs.
