In-Process Analysis of Melt Pool Fluctuations with Scanning Optical Coherence Tomography for Laser Welding of Copper for Quality Monitoring
Optical coherence tomography (OCT) is an inline process monitoring technology for laser welding with various applications in the pre-, in-, and post-process.In-process monitoring with OCT focuses on the measurement of grandpas best weld depth by the placement of a singular measurement beam into the keyhole.A laterally scanned measurement beam gives
