Does anyone know if AWS has a SWPS for metal core wire? Is the use of metal core wire still considered GMAW? I don't have my code book with me to look it up and was asked about this. Thanks for any info.
If your doing standard production work why not consider a Prequalified WPS.. As far as D1.1 2008 goes, MCAW electrodes are still considered GMAW process.. See table 3.1
I'm told that the MC electrodes will be moved from the GMAW back to the FCAW AWS A5 books, BUT that they will still be considered GMAW. Not sure how they'll pull that off.
