Investigation into the intergranular corrosion behaviour of electron beam welded Hastelloy C-276 sheet using laser displacement sensor

The laser displacement sensor scan technique proposed in the present study helps to calculate the corrosion rate (CR), and subsequently, determine the susceptibility to intergranular corrosion, without preparing separate samples for the weld zone (WZ), adjacent heat affected zone (HAZ) and unaffected base metal (BM). Processing of the displacement data collected during laser displacement sensor scan of the electron beam welded Hastelloy C-276...
