Hi Everybody,
I have a question. I have 1 PQR qualified follow AWS D1.1 used to electrode of conpany A. (Exam E7018 of Lincoln). Now I want to change the electrod of company B (Exam: E7018-Li). Do I need to Re-qualify? please explain to me. I fond in D1.1 and checked essential variable table 4.5, They only said, if we change to an electrode of flux electrode classification not covered in A5.1 to A5.5 and then we do Re-qualify PQR.
