RA Power Solutions Pvt. Ltd. deputed team of technicians with consumables. The broken pieces were assembled and metal stitched/metal locked. Total broken area was 46 inches. The broken pieces were re-assembled and metal stitched due to shortage of time and to put on the generator in minimum possible time. The other alternate option  was to use the new piece of casting which was not done in this case due to shortage of time.
