Hello,
I have one question related to a WPS for A351 CF8M (basically a cast 316SS version).
The PQR was performed with a PWHT (solution annealing and water quenching) to 1075°C (1967°F), with impact test.
Given that QW 407.2 refers to QW 407.1, and the P no. of the base metal being 8, the...
Dear All,
hope the question is not too basic.
I have in front of me an inspection and test plan (ITP), on which customer has placed, in his column, a series of H,W,R (to which I am quite used to), and a "M". I know it stands for "Monitoring", but it's not clear to me how I should handle it...
Dear All,
I have lately submitted (for a new Project) a previously qualified WPS+PQR (according to ASME IX).
At PQR stage I carried out a certain no. of impact tests, reporting the results as energy absorbed [J].
Now, my accurate customer is rejecting the PQRs because project specification...
Dear All,
I have to qualify two welding procedures involving following base materials
1)one WPS for A995 GR 4A (UNASSIGNED) to A182 F51 (P No. 10 H Gr 1)
2)one WPS for A995 GR 4A (UNASSIGNED) to A995 GR 4A (UNASSIGNED)
Are both WPS qualified by a PQR in which base materials are
A995 GR 4A...
Dear All,
I have one question. Our welder is carrying out a qualification of a new WPS, by welding a cast coupon in duplex 2205 with duplex 2209. The welding activities shall be distributed during 5 days.
To reduce to minimum the presence of humidity on the weld, the welder shall lightly...
Dear All,
we have produced one sand cast body acc. ASTM A494 CW12MW (corrispondent of Hastelloy C276); it's a pressure containing part, therefore customer requested us to carry out an impact test at T=room (not requested by ASTM A494), guaranteeing 27J minimum.
Now, we have carried out the...
Dear all,
I have the following question:
is there an annex in API 6A which gives guidelines on how to carry out heat treatment furnaces uniformity survey? (no. of termocouples to be used, their position, etc?).
If so, could you specify the exact reference in the code?
Thank you in advance for...
