Abstract

A sensor system for process monitoring of laser welding has been developed, based on coaxial detection of light produced in the welding keyhole. Two detection techniques are used in parallel, the first uses an optical fibre to collect light and guide it to discrete photodiodes, whilst the second uses a high speed camera to image the welding keyhole. This system has been developed for Nd:YAG welding of aeroengine components. Detection of focal errors and state of penetration are demonstrated for Inconel 718 and Titanium Ti-Al-6V.
