Abstract :
It is suggested using arc brazing to attach the cooling pipe to the ITER magnet supports system due to the high bond strength as well as the good thermal conductivity. A microcrack, which is terrible for system safety, was found during the test. In this paper, the mechanism of the microcrack during arc brazing is investigated.
