Steam turbine having applied novel erosion resistant surfaces and methods for applying these surfaces |
摘要 |
Methods for providing erosion resistant surfaces to carbon steel turbine components are provided by this invention. The methods include welding a steel weldment comprising at least 12 wt. % Cr. on to a carbon steel steam turbine component at a welding speed of about 24-52 inches, 61-132 cm, per minute in a nominal first pass thickness of less than about 0.1 inches, 0.25 cm. Preferred flux-cord-arc welding (FCAW) techniques are disclosed for vertical down, overhead, horizontal and flat surfacing positions.
