Abstract : A complex-problem of production practice was presented by the shaping of large-dimensioned parts of the welded-shell type from heat-resistant and high-strength alloys and ensuring that they are made to high precision. The methods used previously to fabricate these parts were laborious and not productive; they did not deliver the necessary precision and required heavy physical exertion. Such components are now being fabricated with high efficiency by tension shaping with expansion punches on special presses. The present paper presents theoretical and experimental investigations of the process of closed-contour shell shaping by expansion-punch stretching, together with basic recommendations for its use.
