[MW:6180] Re: SAW Wire Test certificate review

The last three replys to this post are incorrect. Solid wire is
classified only by chemistry as indicated in my earlier post. Please
read SFA-5.17 paragraph 3.1(c).

This provision recognises the fact that it is the flux that is of
primary importance in determining the mechanical properties for a
given wire chemistry and is stated in the flux-wire classification, as
determined by the flux manufacturer. Unless restricted by customer
specification, any manufacturers wire properly classified wire by
chemistry may be used with a flux classified with that wire
chemistry. Your PQR will verify that it meets your design
requirements, which, with regard to impact testing may be at higher or
lower temperature than that certified. Thus, if you qualify for
example ESAB OK Autorod 12.22 (EM12K) with say ESAB Flux OK 10.71 the
classification is F7A5-EM12K. Per ASME IX, you may use any other wire
certified EM12K (chemistry only) - such as Lincoln L61 (EM12K).

That is what ASME requires - your customer may have much more
stringent requriements. For example, he/she may require that only the
same brand and type of wire and/or flux be used in production as was
used for qualification. Or, they may require each lot and/or heat
number be tested for flux and/or wire.

Again the bare wire is supplied with chemistry only!

The flux, if classified, will be supplied with mechanical properties
for given wire chemsitry(ies).
