Abstract
Austenitic steel welded structures are widely used in power stations, petrochemical industries and nuclear industries. These welded structures pose unique problems for ultrasonic testing not experienced with ferritic steel welds. Since X radiography cannot be used in many cases (like inservice inspection, thick welds, planar defects, etc.), it becomes imperative that ultrasonic testing be used. To do this, the problems encountered during examination of austenitic steel weldments must be understood and solved.
