PREPARATION TO PROGRAM CARRYING OUT OF TECHNOLOGY QUALIFICATION OF BERYLLIUM ENCASEMENT VACUUM INDUCTION SOLDERING FOR COMPONENTS OF ITER REACTOR
Abstract and keywords
Abstract (English):
A process of rapid vacuum induction soldering of the beryllium encasement of inner-chamber components for a thermonuclear reactor is considered. The soldering technological peculiarities, methods of control and tests of soldered joints are analyzed. Basic reasons in the defect formation and corresponding solutions used to increase joint quality are considered.

Keywords:
inner-chamber components, first wall panels, beryllium encasement, qualification, vacuum induction soldering, amorphous ribbon solder
