This paper focuses on the distortion problem faced during the welding process of the divergent section of
nozzle of High Speed Testing System. The High Speed Testing System is a system used to test the scaled models of rockets
and missiles to determine how the actual model will perform in the atmospheric conditions of outer space at that speed.
NOZZLE which helps the system in creating such conditions is considered the heart of the system and has to be
manufactured with a great accuracy and care. As heat is involved in the welding process of nozzle, some distortions are
caused due to it. This paper gives solution to one of such distortion which can be used not only for the welding of nozzle
but also for any components which are to be welded to each other at an angle using the same logic.
