Dear All,
-- I have a doubt from ASME Sec. IX as mentioned below , please clarify.
Welding Process : SMAW
Electrode used in PQR : E7018-1 (Kiswel)
Toughness Test : Applicable
So as per Table (QW-253) - QW 404.12 is supplementary essential variable
Electrode available Now : E7018-1 H4 (Oerlikon) & this has to be used in production now.
Suggest whether the manufacturer of welding consumable can be changed with same electrode classification or new PQR has to be Qualified.
