The Evaluation of Preheat and Post-Heat-Treatment of Welds on Thin Sections of Steel NE 8630

Abstract

Three methods are in current use for obtaining adequate ductility in aircraft steels such as NE 8630. A study of these methods showed that welding both with and without preheat produced a low ductility acicular structure in the heat-affected zone and that both isothermal postheat and torch "stress relief" treatments resulted in more desirable microstructures and excellent ductility.
