摘要：
This paper deals with the investigations carried out to understand the effect of microstructure and weld geometry on the ultrasonic evaluation of single side welded thick austenitic butt weld between ferritic components. The edge faces of the ferritic components are buttered with inconel and stress relieved prior to inconel butt welding. This special process permits welding of buttered ferritic steel for which no stress relief is needed. Velocity variation, attenuation and beam skewing estimated on weld samples and the pattern of distance amplitude correction curves established are analised with respect to weld structure.
