Heat Source - Materials Interactions during Fusion Welding.

Abstract

This report summarizes the first year of progress in studies involving vapor emission from weld pools, design of an infrared microscope for measurement of the weld surface temperature, ultrasonic detection of the weld pool shape, surface reflectivity of aluminum, signal analysis of the weld noise voltage and reflectivity of aluminum by a carbon dioxide laser. The results to date are preliminary. (Author)
