Dear Sirs,
When I read standard JIS B 2220:2004 that required:
Materials of the flanges shall be the ones given in table 5 or those at least equivalent to them in both the mechanical properties and corrosion resistance. (Table 5 : please see attached file)
I don't now what "at least equivalent...
Dear Mr weldstan,
In MILL'S CERTIFICATE by Supplier, Al was not used. So PWHT will be applicable or not. Can you give me advice anymore?
Thank you for your time.
Dear Mr pradipgoswami,
For welding electrodes, I am going to used to FCAW-AWS A5.29 / ASME SFA5.29 E91T1-K2C which is designed for the welding of low alloy steel such as 600Mpa grade high strength steels. So can you give me advice anymore?
Thank you for your time.
Dear Mr metengr and Mr weldstan,
I will perform two weld coupons with and without PWHT following to your instruction(near 1050 deg F).In my contract, it's not require hardness requirements. And how to determine a maximum interpass temp? Could you spare a moment?
Thank you for your time.
Dear Mr metengr and Mr weldstan,
When I received CERTIFICATE from supplier, I was able to locate a copy of the MILL'S CERTIFICATE:
C 0.10%
Si 0.22
Mn 1.52
P 0.11
S 0.03
Cr 0.13
Nb 0.02
Ni 0.01
V 0.06
Ceq 40
YS 598 N/mm2
UTS 694 N/mm2
EL 44%.
In my opinion,I think that it looks like to SA 724...
Dear Mr metengr,
I'm sorry to bother you, but when I reviewed MILL'S CERTIFICATE but it didn't state the austenitizing temperature and tempering temperature. And "Information to be supplied by the purchaser" prescribed by ISO 9328-6 which didn't require this information. So I don't now what is...
Thanks Mr metengr,
OK, I will perform two weld coupons with and without PWHT following to your instruction. But when I looking for the minimum tempering temperature of the PT610Q in ISO 9328-6 and MILL'S CERTIFICATE, I can't find it. So, can you show me where to go look for heat treating...
Many thank to Mr metengr.
I'm trying to follow ASME Section VIII, Div 1. It is mandatory following to my contract. So I qualified WPS following to ASME section IX using the actual material designation. But when I looking for temp. and holding time for PWHT in Section VIII, Div 1 Part UHT, I...
Hi everyone,
Can you support me in welding requirements with thickness 32 mm in sphere tank following ASME VIII div 1 with teachnical specification: Material is Steel grade PT610Q (ISO 9328-6, Weldable fine grain steels quenched and tempered) Yield strength min. 490 Mpa, Tensile strength min 610...
Dear Seniors,
I would like to ask about the pressure change due to temperature change of the test water shall be calculated by using which is formular?
Thank & Best Regards
Hi everyone.
When I supply pWPS to Contractor for review. He write comment in my pWPS that : due to hardness consideration Contractor advise to use an E 8016 - XX electrode instead of E 9016-G. I don't know why. Hereafter is parameter of pWPS:
+Base metal API 5L X65
+Process GTAW+SMAW
