RE: [MW:23124] Change of Brand for SAW Consumables

To Everyone in Welding and Materials Community,

 

This query has generated many responses, many just on the fly some are detailed. SAW is a key welding process for any good fabrication related work. FLUX is the key to any SAW process, more than filler wire. Hence a change of flux is considered as an essential variable.

 

Wire flux classification test is done by manufacturers in undiluted test pads or groove joints (see SFA 5.23). Those results vs. the the PQR results differs in many instances, due to dilution ,heat input........etc.

 

Hence if the flux is changed the PQR should be prequalified.

 

ASME interpretations are one or two lines, many be a short paragraph with a lot of inner meanings.

 

Perhaps a spread sheet with all the pro and the cons would be beneficial to all.

 

Also I would like to say the question is open ended. If one is asking an engineering solution, design code, specifications, technical requirements all needs to be considered, which is missing for many queries off late.

 

Thanks.

PQRs are welded to filler metal and flux classifications not brand names.

No in classicification, only brand name is changed which is not essential for no impact requirements. It can be used

Question: For submerged-arc welding, can a fabricator use a different brand of flux than that specified in a wire-flux classification for which he is qualified, without performing a new PQR?

Reply: No.

Dear All,
We have PQR of following details:

 

Process SAW with Filler Wire EM12K (ESAB) with Flux F7A8 (ESAB OK 10.62 Flux)

 

Question:
1.       Can we use Filler Wire EM12K (Bohler) with Flux F7A8 (ESAB OK 10.62 Flux)
2.       Can we use Filler Wire EM12K (Bohler) with Flux F7A8 (Bohler Flux)

 

Kindly advise as per ASME Sec IX…with reference.

 

Thanks in advance

 

Thanks & regards
