Subject: [MW:15415] electrode change without requalification

 

Dear friends,

 

is it possible to change an E7018-1 electrode to E7018 in a WPS without requalification.

Charpy V notch test value is applicable in this case.

Code is AWSD1.1.

I found in table 4.6 in AWSD1.1 as changing of  electrode  is possible with the same SFA number and F number and A number.

Please advice..........
