Development of new UWND T methods , remote operated vehicle ( ROV )technology and their applications to underwater testing of welded seams were described. The prospects of UWND Ttechnology were also given.Keywords :Nondestructive testing ; Underwater welding structure ; Remote operated vehicle, [1 ] ,:2004205219:(50175027)1 UWNDT 1. 1 UWNDT ,( ,U WND T ,( ND T) ,) , U WND T (U WV T) (U WM T) ( ( U WU T ) ) , (U WR T) (U WND T) ( ( ROV) ) , 1. 2 UWNDT , U WND T ND T ,, ,,U WND T , , ,, [2 ] 1. 2. 1 ,,2005 27 4 207© 1995-2005 Tsinghua Tongfang Optical Disc Co., Ltd.
