Yes you can weld P8 to P8 with E309 and qualify for SS as per F no , In GTAW F no 6 qualifies for Cs and SS also

Mr. Dale Jones
As you said to weld with F5 stainless steel filler material which is needed to weld with matching filler on P8 materials.I would like to add more...i.e. as per QW 423 Alternate Base Materials for welder qualification we can weld P1 materiel also with F5 SS Filler in order to qualify welder for any particular P8 WPS.
This is economical as well as within limit of code.
Please correct me if my interpretation is wrong

| This is correct that the welder can weld on all of these materials but do not ignore the other variables. For example the welder will be restricted to the Fnumber filler material he qualified with. An example is a SMAW qualification. When a welder qualifies on P1 material with a matching F4 SMAW filler he will be qualified to the base material range stated below and with F1-F4 carbon steel filler material. This will not qualify him to weld with F5 stainless steel filler material which is needed to weld with matching filler on P8 materials. The same concept will apply to various other P numberd materials. To fully understand this concept and the other variables that will restrict a welders qualifications, read article 3 and QW-416 in ASME Section 9
Not only P11. Also P34 & P41 thru P49. The reason is, the skill of the welder required to weld any of these material is same. So he can proove it in any one P No. mentioned . Regards, Muhammed Ibrahim
