Dear Mr. Mahesh Yes you are correct, if the welder is Qualified in P1(CS) he is qualified to weld all metals of P‐No. 1 through P‐No. 15F, P‐No. 34, and P‐No. 41 through P‐No. 49. Since SS material falls in P8, the welder can weld SS Base Metal also.

Dear Mr. Madheswarn Since you haven't mentioned the Code Reference, I'm considering ASME SEC IX which is widely used in the industry. As per ASME SEC IX, if the welder is qualified to weld the filler ER70S2, which falls under F-Number F6, he can weld all the filler which falls under F-Number F6, as per QW-433. Since ER316 and other filler wires of SS fall under F-Number F6, the welder can weld these SS Filler wires. Note that other essential variables shall also be noted like Backing, Purging which depends upon the Welding process. Also please note which Code is referred and based on that this qualification also changes.

Some contractors use the essential variable tables (QW-352 thru 357) to minimize their costs. For instance, they might test the welder for stainless steel material by using carbon steel material. Consider the actual project material is stainless steel and you do not want to waste stainless steel material for testing. You ask the welder to weld in carbon steel material but with stainless steel filler metal. Ø Based on the essential variable table P number 1 (Carbon Steel) qualifies P 8 (Stainless Steel), and the Ø   F number is the same. Ø So you qualify your welder for stainless steel material by using carbon steel material but stainless steel filler metal . Ø Adding back gas(purge gas) for SS welding - NO ESSENTIAL VARIABLE On Saturday, 30 July 2022 at 17:01:17 EEST, srinivas rao <engr.srini@gmail.com> wrote: ...

Dear Madheswaran , As general understanding of code  ,If the Essential variables of CS qualified by the welder are not changes, then the welder is allowed to weld SS material as permitted by the ASME SEC IX , QW-423, There is only one major change in SS welding is back purging(backing). A welder qualified without backing, can weld with backing as per ASME sec IX this is only limited to GTAW process/the process where essential variables are not changed So a welder qualified in CS without purging can weld SS with purging. But one has to consider other variables like are this welder cable to do welding in case of purging, is he aware of welding variable, other welding requirements to be followed for material mainly inter pass, travel speeds. Considering the base material chemistry , metallurgy and criticality of the job one shall not allow CS qualified welder for SASS, DSS, SDSS welding even though code permits. thanks& regards, Srinivas Rao Welding Engineer...

Dear Experts , ASME SEC II PART D - The Table for Non ferrous materials is referred.  For one of SB 564 Flange material- Ni based alloy UNS6625  , we come across following note :  G22-The minimum tensile strength of reduced section tension specimens in accordance with QW –462.1 of Section IX shall not be less than 110,000 psi.
