Dear All
-- I have query about use of Electrode with change og classification
We have WPS for SMAW welding process for P1 material with the E 7018 electrode in that case can we use in production E7018-1 electrode
Please help me out in interpretation
QW 404.12 (e) from a classification that requires toughness testing
to the same classification which has a suffix which indicates
that toughness testing was performed at a lower
temperature or exhibited greater toughness at the required
temperature or both, as compared to the classification
which was used during procedure qualification (i.e., a
change from E7018 to E7018‐1)
