ASME Sec II Part A states that the chemical composition of SA/A516 Gr 60 for Mn is 0.79 - 1.30 but a steel manufacturer states their product meets ASME spec but is 0.79 - 1.50 Mn. Does ASME allow a tolerance for exceeding the Product Analysis?
I am getting differing opinions on several forums as to the extent of RT as it applies to 70% JE.
After much feedback I'm leaning to the assumption that butt welds in the circ and longitudinal shell joints of a tank require Spot RT when 70% JE is called out in the Design Data block of the AFC...
I know ASME Sec VIII Div 1 per UW-12 does not require RT for 70% JE on double welded butt joints.
Does API 620 per Table 5-2 require RT for 70% JE on double welded butt joints?
Thanks in advance for your assistance.

In the title block of the tank drawing it states the engineer that:
Drawn By: MG
Checked By: LPJ
Approved By: KPS
Which of these persons is considered the EOR?
Appreciate your comments,

We have qualified WPSs to join 2205 to 2205 with 2209 filler metal and C276 to C276 with ERNiCrMo-10 filler metal. I believe the correct filler metal to join 2205 to C276 is ERNiCrMo-10 filler metal however the 2205/C276 will be subjected to a variety of atmospheric harsh acids and am concerned...
Would like your opinion (or best guess) on what filler metal and welding process you would use to stitch weld a bushing to the flywheel of a motorcycle?
Please see attached sketch of crankshaft part assembly and PMI of flywheel and bushing.
Thank you your time

A company purchases and receives a full coil (approx. 26 sheets) of stainless steel plate.
One MTR accompanies the lot and it states "Qty 7 sheets" with Ht No 34645.
Is it acceptable to approve the remaining 19 sheets that are identified as Ht No 34645?
Thanks in advance,
Robert
I know that a company is not required to be certified in order to manufacture & sell API12F tanks but would like some input from someone with experience with 12F certification.
I have heard that the cost of becoming a 12F certified company involves much more than an ASME "U" stamp cert and much...
Could you help me on where to find the max hardness value after post weld heat treatment of P4 & P15E materials.
the construction codes are either B31.1 or ASME sec 8, we have done a welding procedure qualification test and we got some hardness values, but do not know whether the hardness...
Good afternoon Gents,
What a wonderful, invaluable forum this is that we can draw on the knowledge and experience of such a vast audience of forum members.
I am investigating GMAW process equipment that will exert the least amount of thermal input into welding a .750" thk rolled CS flange to a...
Anyone here have experience in removing weld anti-splatter from stainless steel in order to paint the weldment?
After using solvent and then power washing areas with anti splatter, the then painted areas seem to leach out the anti splatter and create a fisheye appearance.
Thank you in advance.
Hello,
As QA manager of a pressure vessel fabrication facility, I am researching the ISO 9000 & 9001 for our company and to be honest am somewhat skeptical as to its value to our company.
We already have in place the ASME U & PP stamps and NBIC R stamp certifications.
I could see where ISO...
Gentlemen,
On the laser table we use a 55% Nitrogen, 40% Helium, 5% Co2
Was wondering what is the ideal gas for plasma cutting G-30 Hastalloy material?

We have a Client that we are building a non-stamped vessel (under 15psig and non-lethal and 1/2"-5/8" thk) to ASME Section VIII Div 1.
Client has stated all welds in material ½ in. (13 mm) and greater in thickness may be examined using the ultrasonic (UT) method given the requirements of 7.5.5...
Have a vessel, non lethal service, non code stamped, that was designed per Sec VIII Div 1. Client wants spot RT to fullfill 85% joint efficiency. I, as manufacturer, have proposed 100% shear wave UT to give overall better information on all weld seams. Client agrees but wants me to provide...
I have a contractor stating that his welder is qualified to weld unlimited thickness because his WPQ utilized a pipe thickness of 0.500” as per ASME QW-452-1(b).
I disagree in that I interpret QW-452.1(b) as to state that ALL thickness (t) of weld metal in the Coupon qualifies only to 2t. The...
