Abstract
A method and apparatus for real-time determination of weld quality. A collimated light source 10 directs a beam 16 of collimated light to a point on the weld pool surface 24. A position sensor 34 measures the direction of the light after it is specularly reflected from the weld pool surface 24. Electronic means 36,38,40 analyze this measurement for determining changes in angles of the weld pool surface 24 for real-time indication of the state of penetration of the weld pool 26.
