Thermal diagnostics for monitoring welding parameters in real time

The use of sensors in arc welding processes is typically complicated by the intense light and electrical noise emanating from the arc. In consumable electrode processes, data acquisition is further complicated by the generation of metal spatter. The objective of the current work was to develop noncontacting diagnostic techniques for monitoring temperatures during arc welding. The purpose of the diagnostics was to provide experimental data for both weld model input and computer model verification for gas metal arc (GMA) welding. These techniques have also been applied to gas tungsten arc (GTA) welding.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.
