A guy tests out using F3/F4 on SA106B 6" Sch 80 coupon.
He gets a ticket that says he is qualified in base materials P1 - P11, P15E and in many places in Ab, that is governed by whether the company he works for actually has Qualified-Registered Procedures with ABSA for those base materials. So assuming his company does...
....why would that qualify him to weld 316L or Duplex base materials given that the elctrode class is F5 for Austenitic SS and Duplex.???
No place in the 35 years that I have been working, first a welder, and in the later years as a CWI (CWB Level II), have I ever seen those base materials welded with F4 electrodes. This does not make sense to me.
I can see this guy being qualified to weld P1-P5X,P9,P10A,B,C, P11X-P15X...but not P8-P10H (as an aside, I think the 10H grouping should be changed to P8 with a subset.)
Somebody explain to me the reasoning of this change in Sect IX .. of taking the F4 electrodes and splitting these up in to two seperate groups such as F5 and F4 while talking about essentially the same Filler metal specification SFA 5.4.??
Where they not, if memory serves me correctly correct...all in F4 at one time..?
Am I out to lunch here or just gettin too damned old...LOL.?
Thank you,
