.... The application for the overlay was the repair of cavitation erosion damage on a large Francis turbine used in a hydroelectric project. The overlay weld consisted of a 4 × 6 pattern of 100 × 100 mm 2 squares. Each square was covered by 15 weld passes. Each weld pass was 100 mm long. The total length of weld...
