In situ strain monitoring in gas tungsten arc welding processes


Strain/stress evolution during welding is essential to understand material's mechanical behavior and the formation of weld defects such as distortion, cracks and residual stresses. In-situ measurement of strain has been very challenging due to the impact from high temperature and intense arc light. In this work, a newly-developed integrated optical system… (More)
