About

Spacecraft propellant tank is a Ti6Al4V alloy construction. The Electron beam welds of thickness 3-4 mm are to be evaluated for porosity, cracks and LOF. The present NDE techniques cater to defect detection in the welds after welding, many a times there are possibility of reworks that take time and effort in choosing the location for rework as the hardware would have been un-mounted from the weld set-up. A technique in-situ the weld chamber to evaluate the weld during welding in vacuum is being developed using thermal imaging in order to detect and characterize the defects.

Achievements

The project being undertaken by ISRO in collaboration with academia is directly or indirectly beneficial to the society.
