Pre-Welding Analysis and Associated Laser Welding Methods and Fiber Lasers Utilizing Pre-selected Spectral Bandwidths that Avoid the Spectrum of an Electronic Transition of a Metal/Alloy Vapor

摘要

The present invention benefits from the determination that pre-selected spectral bandwidths that avoid the spectrum of an electronic transition of a metal/alloy vapor allow for welds substantially free from detritus that may discolor the weld. Accordingly, the present invention provides analytical methods, welding methods and fiber lasers configured to provide high quality metal/alloy welds.
