BLANK FOR DIFFUSION LAP-JOINT WELDING OF TUBULAR ADAPTERS

摘要

FIELD: designs of blanks for diffusion lap-joint welding of tubular adapters of different type materials. SUBSTANCE: tubular blank is formed of two different type sleeves. The last are preliminarily elongated. It allows simultaneously with diffusion welding of adapter blank to perform welding of reference ring - sample. Due to using destruction method for testing reference ring - sample, it is possible to provide objective evaluation of diffusion welding quality of tubular adapter. EFFECT: improved design of blank providing reliable evaluation of welding quality of tubular adapters. 4 cl, 4 dwg
