The application of the repair brazing is based on the effect of an activated diffusion interaction between particles of a composite brazing alloy and surfaces joined, being a result of a contact fusion of surface of particles and part wall by a low-melting component of the brazing alloy, and also by a post heat treatment of the brazed joint at temperature, lower by 80-120 [degrees]C than maximum (approx.
