Abstract:
A method for repairing indications open to a surface of an article, comprising the steps of:cleaning a surface of the article;applying a fluorescent penetrant to the surface of the article;visually inspecting the surface of the article under normal lighting conditions at preselected levels of white light to detect areas requiring repair; thenapplying repair alloy to the article in preselected areas requiring repair as identified by visual inspection; theninspecting the surface of the article under ultraviolet light at preselected levels to detect areas requiring repair detectable by the fluorescent penetrant and not readily detectable by visual inspection; thenapplying a repair alloy to the article in preselected areas requiring repair as identified by fluorescent penetrant inspection under ultraviolet light and visual inspection under white light; andplacing the article in an elevated temperature atmosphere sufficient to liquify at least a portion of the repair alloy, so that the repair alloy flows into the areas requiring repair.
