Photodiode-Based In-Process Monitoring of Part-to-Part Gap and Weld Penetration Depth in Remote Laser Welding of Copper-to-Steel Battery Tab Connectors

Available to Purchase

Giovanni Chianese, Pasquale Franciosa, Jonas Nolte, Darek Ceglarek, Stanislao Patalano
Proc. ASME. MSEC2021, Volume 2: Manufacturing Processes; Manufacturing Systems; Nano/Micro/Meso Manufacturing; Quality and Reliability, V002T06A016, June 21–25, 2021
Publisher: American Society of Mechanical Engineers
Paper No: MSEC2021-63321
https://doi.org/10.1115/MSEC2021-63321
... Abstract This paper addresses in-process monitoring of part-to-part gap and weld penetration depth using photodiode-based signals during Remote Laser Welding (RLW) of battery tab connectors. Photodiode-based monitoring has been largely implemented for structural welds due to its relatively low...
