Electrode 80S-B8 for GTAW & El
Electrode 80S-B8 for GTAW & El
(OP)
Electrode 80S-B8 for GTAW & Electrode 8018-B8 for SMAW. to be used FOR WELDING A335 P9 PIPE MATERIAL.
Electrode 80S-B6 for GTAW & Electrode 8018-B6 for SMAW- used elecrode.
We have done welding & installed in site “A335 Grade 9 pipe material” with existing WPS with above electrode B6.
This happened because all Parameters like P No.,F No. & A no. are matching with existing WPS & Mechanical properties Strength (60 KSI, Minimum) is also matching.
Only slight difference in chromium & Molebdenum Electrode
What is the solution for this?

If Pipe line(P9 MATERIAL ) connecting to Tie in is P5 material than any excuse for cut and welding ,MONITOR means what ,can you detail it ?
ASME SEC 9 Table QW-442 Says A5 material chrome 4% -10.5%(classification of ferrous weld metal analysis for procedure qualification),can we consider this for acceptance of PMI results.

If it were my piping, I'd have every weld cut out and personally run off whoever tried to weasel their way out by claiming the A number limits as PMI limits. That's just me though...
