With reference to your quires, answers as follows:
1) If 7018-1 is consumables used for WCB & LCB (casting Form) & is meeting the
impact values at -46 deg C.
Welding of A 216-WCB to WCB : SFA-5.1 (AWS-E7016) for SMAW ( alternative
SFA-5.5 AWS-E7018-A1)
SFA-5.18 ER70S-6 for TIG
Welding of A 352 LCB to LCB : SFA-5.1 (AWS-E7016) for SMAW ( alternative
SFA-5.5 AWS-E7018-A1)
SFA-5.18 ER70S-3 or 6 for TIG (alternatively SFA-5.28 ER70S-A1
2) What will the Consumables shall be used for Single V BuTT joint of 2 pieces to be joined for
WC6 to WC6 , WC9to WC9 & CF3 to CF3 base Materials?
a) Welding of A 217 WC6 to WC6 : E 8018 B2 ( for SMAW) and ER 80 T5-B2 (for TIG) are
recommended since the base metals are having 1.25 to 1.50 Cr & 0.45 to 0.65 Mo. The
matching chemistry is important.
Welding of A 217 WC9 to WC9 : E 9018 B3 ( for SMAW) and ER 90 T5-B3 (for TIG) are
recommended since the base metals are having 2.25 to 2.50 Cr & 0.45 to 0.65 Mo. The
matching chemistry is important.
Working Temp. for both are from -30degC to +593 deg. C
Welding CF3 to CF3 : E 304L ( for SMAW) and ER 304L (for TIG) are recommended
since the base metals are having 19 to 21 Cr and 8 to 12 Ni. The matching chemistry
is important.

3) Any Special Consumables are used to meet Impact test Values of -29 & -46 Deg C of
Above materials as mentioned?
E 7018 /ER 70 S2 will give impact up to -30deg C.
E 7018-1 (or) E 8018-1 or E 8018G will give impact up to -46 deg. C.

Dear Shridhar,
Query on folllwoing points as mentioned (As per your last mail on ) :-
1) If 7018-1 is consumables used for WCB & LCB (castinf Form) & is meeting the impact values at -46 deg C.
a) What will the Consumables shall be used for Single V BuTT joint of 2 pieces to be joined for WC6 to WC6 , WC9to WC9 & CF3 to CF3 base Materials?
b) Any Special Consumables are used to meet Impact test Values of -29 & -46 Deg C of Above materials as mentioned?
Please , reply to my quireies.
With Regards,
ASHISH
Agree with what others have said But, before proceeding with another coupon plate welding, please check out,
1. whether the consumables you are using/have used, shall meet the impact
values at -46 deg C. If not the entire exercise will become futile.
2. Whether the base metal selected earlier could meet the said impact norms , if not it may
not be required to do -46 deg. C impact for consumables used.
3. ASME sec IX does not ask for hardness as such. If you have done hardness test for
your jobs, you could be following ISO 15614-1 or any equivalent code, then you may
require impact for base metal, HAZ apart from the weld zone.
4. Pl. check up before proceeding further.

--Dear experts,--
Please help out to clear my doubt.
I have qualified a WPS/PQR with impact -29 deg C, now customer want the WPS/PQR shall be qualified with impact in -46 deg C. Also there is no remaining coupon piece available for impact testing with -46 deg C.
My question here is, should I weld a coupon and only do impact test as required by customer and attached to PQR will be sort out this issue.?
or
Should I REDO a PQR with all mechanical test which includes Tensile, Hardness, Bend along with impact will sort our this issue.?Requesting you to please provide me ASME IX clause reference.
Anticipating for you kind help.
Thanks & Regards.
M.K.Mubeen
