Operation
5.10 Classification of welds
(function group AWS)
You can rate flaws in welds according to the specifica-
tion AWS D1.1. You will find the corresponding functions
in the function group AWS.
– If necessary, change to the second operation level.
– Select the function group AWS.

Rating of welds according to AWS
The rating of flaws in welds according to the AWS
specifications is based on an evaluation of the signal
amplitude. In this process, the echo amplitude of the
flaw echo is compared with the echo amplitude of a
known reference reflector. In addition, the sound attenu-
ation in the workpiece is also taken into consideration.
The result is a dB value which is called flaw rating. The
flaw rating D is calculated according to the formula:
