Abstract

Способ диффузионной сварки телескопических соединений за счет разницы коэффициентов термического расширения материалов свариваемых деталей и оснастки, при котором наружную деталь устанавливают в обойму из материала с меньшим коэффициентом термического расширения, чем у свариваемых материалов, в нее устанавливают внутреннюю деталь, нагревают до температуры сварки, производят изотермическую выдержку и контролируют качество сварки, отличающийся тем, что, с целью повышения качества соединения с одновременным его контролем при сварке деталей из материалов с соотношением коэффициентов термического расширения, равным 1,0-1,1, на наружной поверхности внутренней детали выполняют продольный паз, по изменению профиля которого определяют качество соединений.The method of diffusion welding of telescopic joints due to the difference of the coefficients of thermal expansion of the materials of the parts to be welded and the equipment, in which the outer part is installed in a cage of a material with a lower thermal expansion coefficient than the materials being welded, the inner part is installed in it, heated to the welding temperature, isothermal holding and controlling the quality of welding, characterized in that, in order to improve the quality of the joint while simultaneously controlling it during welding, Etals from materials with a ratio of thermal expansion coefficients equal to 1.0-1.1, on the outer surface of the inner part a longitudinal groove is made, according to which profile change the quality of joints is determined.
