[MW:28350] Re qualification as per AWS D1.1

Dear All,

I have to re-qualify the welders as per AWS D1.1 but I have some
quires. Please help me to resolve the same.

1) What should be the test piece thickness for re qualification ? Our
previous thickness was 25 mm. ( As AWS shows option of 10 mm thk test
plate which will qualify any production welding thickness )
2) Do I need to go for mechanical testing or only radiography is sufficient?
3) What will be the qualification range after successful qualification?
