چکیده
|
Acoustic emission (ae) signatures of various weld defects of stainless steel 316l nuclear grade weld material are investigated. the samples are fabricated by tungsten inert gas (tig) welding method have final dimension of 140 mm x 15 mm x 10 mm. ae signals from weld defects such as pinhole,porosity,lack of penetration,lack of side fusion and slag are recorded under dynamic load conditions by specially designed mechanical jig. ae features of the weld defects were attained using linear location technique (llt). the results from this study concluded that,stress release and structure deformation between the sections in welding area are load conditions major part of acoustic emission activity during loading.. © school of engineering,taylor’s university.
