Laser Engineered Net Shape processing was evaluated as a means to repair scratched gas sample bottles and mis-machined test bases. Defects to be repaired were intentionally introduced. These defects simulated scratches and holes that had been either over bored or misaligned. These parts were repaired using LENS and then tested in the baseline, as damaged, and hydrogen charged conditions. The effect of LENS repair was not detrimental to the properties of the components. Further development work and implementation of the process is recommended.
