Hi!
As per ASME sec IX
the A No is expected Weld chemistry range and for filler metal F no is designated
Moreover for CS welding, while selection of Filler ,you have to give importance to Mechanical properties and not exact matching of chemistry

Dear All,
I have one doubt.
In section IX A-number specified for mild steel
is 1 and when we see the chemistry of the filler metal in
section II part c the range specified is going beyond the
specified limit Si - 1% and Mn - 1.6% as per section IX.
if a batch of carbon steel filler metal having Sil 1.03
and Mn. 1.6 % then in which A-number we can consider and
shall we qualified a new procedure for this particular batch
and which A-number we will assign.
Thanks in advance,Manoj.
