Tom
Thanks for the Chg. No.; I need it to do my bi-weekly timesheet, which Larry signs.
 
PPPL shop can do both GTAW and SMAW on light structural carbon steel materials. The welders prefer GTAW, but SMAW is faster, so I want to give the shop that option for this application. We would do only GTAW for SS vacuum applications, for example.
 
I agree, we should reference only AWS D1.1 (no specific Section as there are also requirements specified in Sections 2, 3, and 4) in first sentence, and specifically D1.1 Section 6(Inspection) in second sentence.
 
Please call if any questions
 
Bob

Bob - thanks for your prompt reply.  I'm not sure how your PPPL job charge
arrangement is; if you have a "per customer" charge or if you have a PPPL
overhead charge number.  If it is per individual request, my PPPL job number
for this task is: 9450 1*** 1803. I'll check with Larry or Phil to see if
there is a different job number.

I have a question. The parts are going to be fabricated in the PPPL shop
where they generally always use GTAW welding.  Is it necessary to call out
"GTAW or SMAW"?  Also in the PPPL engineering manual that I have attached
(page 27) the only reference is for the inspection of the weld per AWS D1.1
Section 6 (for structural carbon and low alloy steel welding).  Does this
imply that the welding is performed per AWS D1.1 Section 5 and inspected per
AWS D1.1 Section 6?

Tom

Tom,
Comments  as noted re Dwg No. se185-017:
1. Specified process for welding of 1/4" thickness structural carbon steel in
the tail if the welding symbols should be "GTAW or SMAW"
2. First sentence of Note 1 should refer to AWS D1.1 Section 5, in lieu of
Section 6.

What is the applicable PPPL charge number?
Thanks,
Bob

Robert,

I'm going to check the new system out here.  Larry is on vacation and is
unable to review the weld callout in the attached PDF drawing file
(se185-017).  There is a 1/8" fillet weld called out on a couple of parts.
Drawing se1851-019 is the assembly that shows the assembled parts.  Please
review the drawing and give me your approval so I can submit them to the
shop.

Thanks,

Tom
