Executive Summary

This project has been initiated to study and control the Ultra Violet (UV)radiation in welding processes. Experiments were carried out using TIG and MIG welding machines and a UV Spectrometer. The welding gun was driven by a manipulator. Interim results show that a significant amount of UV radiation is emanating from the arc and it becomes negligible beyond a distance of 200 cm from the arc source. Further work is under progress.
