Scope

This document specifies techniques for the manual ultrasonic testing of fusion-welded
joints in metallic materials of thickness not less than 8 mm which exhibit low ultrasonic
attenuation (especially that due to scatter) at object temperatures from 0°C to 60°C. It
is primarily intended for use on full penetration welded joints where both the welded
and the parent material are ferritic.
