Hi weldstan, thank for your reaction.
If I’m right the E7018-A1 is a SMAW electrode.
Think the equivalent for this as TIG rod is the ER80SG with analysis: C=0,1 – Si=0,6 – Mn=1,1 – Mo=0,5
The analysis for ER80 SB2, the one I’m pretended to use for the weld test is: C=0,11 – Si=0,65 – Mn=1,0 –...
Hi DekDee, thanks for your reply, I missed this one...
So if thikness is >13mm I follow PWHT specs for P4
And with thikness <13mm and C<0,15% preheat at 120C and no PWHT nessecary.
Is my conclusion correct?
Hi all,
I have the following issue:
We are going to weld steam traps out of dissimilar material; body cast 16Mo3 (P3) with flanges A182F11 (P4), size 1"XXS (33,4 x 9mm)
Max work. temp. is 415C and max. pressure 80 bar
We need to qualify a PQR for GTAW and Im preparing the following WPS...
Hi All,
Is it allowed to use DIN material like pipes, fittings, flanges, etc. in a pressure vessel according ASME-VIII and pressure piping according ASME-B31?
All parts have double material certificates.
