Fast responsive real-time monitoring of GMA-DED process signatures and their transient variations is required for printing of dimensionally accurate and structurally sound parts. A systematic experimental investigation is presented here on multi-layer GMA-DED with two different scanning strategies using a high strength low alloy (HSLA) filler wire. The dynamic metal transfer, melt pool temperature field and its longitudinal cross-section, and arc voltage and current are monitored synchronously. The transient arc heat input and the melt pool solidification cooling rate are estimated from the monitored signals. The layer-wise variations of the melt pool dimension, surface temperature profile, thermal cycles, and solidification cooling rate are examined for different scanning strategies. It is comprehended that the part defects can be minimized, and the mass production of zero-defect parts can be achieved in GMA-DED process with synchronized monitoring and assessment of the real-time process signatures.}, language = {en} } @misc{DasChaurasiaMandaletal.2023, author = {Das, Atanu and Chaurasia, Prashtan Kumar and Mandal, Gopi K. and Goecke, Sven-Frithjof and De, Amitava}, title = {Sample calculations to estimate joint distortion based on the published article "Analytical Estimation of Thermomechanical Distortion and Interface Layer Thickness for Gas Metal Arc Lap Joining of Dissimilar Sheets"}, year = {2023}, abstract = {A sample set of calculations is presented in this supplemental document to analytically estimate joint distortion for gas metal arc lap joining of aluminum and steel thin sheets following the published article "Analytical Estimation of Thermomechanical Distortion and Interface Layer Thickness for Gas Metal Arc Lap Joining of Dissimilar Sheets"}, language = {en} } @article{DasChaurasiaMandaletal.2023, author = {Das, Atanu and Chaurasia, Prashtan Kumar and Mandal, Gopi K. and Goecke, Sven-Frithjof and De, Amitava}, title = {Analytical estimation of thermomechanical distortion and interface layer thickness for gas metal arc lap joining of dissimilar sheets}, series = {Welding in the World}, journal = {Welding in the World}, number = {76/2023}, publisher = {Springer Link}, issn = {432288}, doi = {10.1007/s40194-01426-x}, pages = {33 -- 49}, year = {2023}, language = {en} } @article{DasGoeckeDe2021, author = {Das, Atanu and Goecke, Sven-Frithjof and De, Amitava}, title = {Joining of aluminium alloy and galvanized steel sheets multimaterial assembly using a gas metal arc based process}, series = {Tecnologia em Matalurgia, Materiais e Minera{\c{c}}{\~a}o}, journal = {Tecnologia em Matalurgia, Materiais e Minera{\c{c}}{\~a}o}, publisher = {ABM - Associa{\c{c}}{\~a}o Brasileira de Metalurgia, Materiais e Minera{\c{c}}{\~a}o}, issn = {2176-1515 (PRINT) 2176-1523 (ONLINE)}, doi = {10.4322/2176-1523.20212464}, year = {2021}, language = {en} }
