So if you normalize after welding with E9018, no problem at all

WHAT IS YOUR THICKNESS?, E9018 MAY NEED PWHT BECAUSE NORMALLY IS NOT USED FOR P1 MATERIALS

Dear Mr. Karthik / Raghuram bathula
My Question is whether the filler metal
(SMAW with E9018-G; SFA 5.5; A=10; F no. 4 & SAW with F9P6 EG F3; SFA 5.23; A=10; F no. 6)
is acceptable to the base metal (SA516 Gr 60) as weld metal chemical properties(C=0.06%, Mn=1.37%, Si=0.24%, S% <0.005, P=0.014%, Mo=0.48%, Ni=0.82%, Cu=0.13%.) are not meeting the SA516 Gr60 requirements.

| Hi, I found the WPS&PQR from your Contractor have used SA516 Gr.&0(P.No.1,Gr.2) but your actual material in production is SA516 Gr.60(P.No.1,Gr.2). Change in Material Group No.is a Supplementary Essential Variable for SMAW and SAW Processes as per QW253 and QW254. Please find below the extarction from ASME Section -IX-QW403.5 for your reference. QW-403.5 Welding procedure specifications shall be qualified using one of the following: (a) the same base metal (including type or grade) to be used in production welding (b) for ferrous materials, a base metal listed in the same P-Number Group Number in table QW/QB-422 as the base metal to be used in production welding (c) for nonferrous materials, a base metal listed with the same P-Number UNS Number in table QW/QB-422 as the base metal to be used in production welding For ferrous materials in table QW/QB-422, a procedure qualification shall be made for each P-Number Group Number combination of base metals, even though procedure qualification tests have been made for each of the two base metals welded to itself. If, however, two or more qualification records have the same essential and supplementary essential variables, except that the base metals are assigned to different Group Numbers within the same P-Number, then the combination of base metals is also qualified. In addition, when base metals of two different P-Number Group Number combinations are qualified using a single test coupon, that coupon qualifies the welding of those two P-Number Group Numbers to themselves as well as to each other using the variables qualified. the heat-affected zone is not required by other Sections.
