FIELD: construction.
SUBSTANCE: billet for carrying out subsequent diffusion welding under hot isostatic pressing conditions contains a titanium and an aluminium billets placed in the capsule. On the welded surface of the titanium alloy billet, a relief notch is made in the form of projections and grooves having the same profile and the same curvature radius equal to 1/2 of the projection height. The number of notch periods on the welded surface of a titanium alloy billet is at least two.
EFFECT: adapter obtained by using this billet has a tight-dense diffusion connection with stable properties due to the uniform distribution of the load applied during the operation, the absence of voltage concentrators and the increased connection area.
