概要
In order to study the influence of welding condition on the detectability of flaws in Ni based alloy by UT, we lding conditions, such as heat input, magnetic stirring and weaving were changed. Flaws in small heat input we ld joints was difficult to be detected because of the presence of high noise. On the contrary, welded joints m ade with large heat input and weaving showed lower noise and EDM notches in these joints were easily detected.
