The runner buckets of one of the runners were severely worn after about 6
months of operation due to the sediment in the water. All buckets
were repaired by building up by welding, followed by grinding and
polishing. The
repaired runner was heat treated to relieve any heat stress from welding
and then checked for its dynamic balance before it was sent back to the
plant.
