F4X qualifications

F4X qualifications

F4X qualifications

(OP)
Hi,

We have a welder with following qualifications:

Process - SMAW
Filler Metal - F4X
Material - P1-P11 & P4X

Is he able to weld using Arctec 661T and Tungcote E?

I think he might be good for Tungcote E but I am not sure about 661T.

Thank you for your responses.

RE: F4X qualifications

F #?

RE: F4X qualifications

(OP)
Not sure what you mean?

RE: F4X qualifications

These are hardfacing filler metals with no assigned F-No classification, the welder can weld using either filler metal. Do you have a WPS qualified for this project?

RE: F4X qualifications

F4X refers to filler metals with a F number of 41, 42, 43, etc. The letter "X" is a place holder representing any digit. F4X refers to any number of nickel based alloys grouped as a F41, F42, F43, etc.

F numbers can be found in ASME Section IX as well as AWS B2.1

Best regards - Al

RE: F4X qualifications

Not if the Trade designations stated are not within the permitted P-Nos. Review Qw-403.18 or as further modified under QW-423.1 and QW-423.2.

RE: F4X qualifications

As is typical, the OP mentions nothing regarding the use of filler metals. Just because ASME Section IX is referenced for welder certification says nothing about welding outside of ASME B&PV Code. For all we know, he is using an ASME qualified welder to apply hardfacing on garbage cans.

RE: F4X qualifications

Thanks metengr.
I originally thought base metals. The OP needs to provide greater clarification. Was the welder qualified for a Hard Surfacing, Corrosion Resistant Overlay, groove weld or other? Furtermore, it is doubtful that the weld filler metals proposed meet the F4X criteria in Table QW-432, in which case, the welder is not qualified to do so.
