The Effect of Welding Angle for Acoustic Emission Propagation in Offshore Jacket Platform

Abstract

Considering the requirement of NDT for offshore jacket platform, the effection of welding angle to the propagation characteristic of acoustic emission (AE) is studied. Amplitude and energy are the main analysis parameters for the experiment. As used wildly in jacket structure, the 90 and 45 degrees welding angle are discussed. The research result can provide references for engineering application of AE technique to locate the damage source and analyse the failure feature.
