[siamak]

Hi Dear Firends
can anyone upload interpretation of ASME SEC IX,different VOlume. I want
file NO BC82-246 and BC82-237 and BC82-265, BC83-284, BC86-337, BC88-474.
Some ASME code like ASME B31.3 has complete interpretation which can be downloaded from asme website but existing interpretation on ASME Sec IX is not complete.
And As a Matter of fact above file NO. is required to find out if weld Reinforcement shall be Considered in determining qualification range of deposited weld metal.

Thanks in advance

Interpretation: IX-83-05
Subject: Section IX, QW-451
Date Issued: July 2, 1982
File: BC-82-237

Question (1): A WPS has been qualified for thickness range of 3/16 in. to 8 in. using a pipe coupon 12.75 in. O.D. with a nominal wall thickness of 1.5 in. Can a production weldment using a base material with a manufactured thickness of 0.178 in. be welded with the above WPS when the nominal wall thickness for this
material was 0.203 in. and the 0.178 in. manufactured thickness is within the 12.5% manufacturing tolerance?

Reply(l): Yes.

Question (2): In accordance with Section IX, does the minimum value of a qualified thickness range apply to the nominal material thickness or the actual thickness of the production weldment material ?

Reply (2): The minimum qualification thickness value applies to the nominal thickness.

Question: A welder has been qualified for a thickness of deposited weld metal from 1/16 in. to 3/4 in. for a particular welding process. A 3/4 in. thick pipe is to be welded in production, using a single-vee butt joint, with the same process for which the welder is qualified. Is a second welder required to deposit the weld
reinforcement, or is it permissible for the welder who completes the weld to deposit the reinforcement?

Reply: A second welder is not required to deposit the weld reinforcement. It is permissible for the welder who completes the weld to deposit the weld reinforcement.

Question: A welding procedure for a particular process has been qualified on 3/8 in. thick material. Weld reinforcement was removed during preparation of test specimens for mechanical testing. A 3/4 in. thick pipe is to be welded in
production using this qualified procedure. May the finished weld include the reinforcement permitted by the Code [for example, Section VIII, Division 1, UW-35(c)], or must the finished weld be flush with the surface of the base metal?

Reply: The finished weld may include the reinforcement permitted by the applicable Code.

Question (1): In qualifying a WPS, may the actual production base metal thickness be used as the weld test coupon thickness?

Reply(1): Yes.

Question (2): In qualifying a WPS to cover 9 mm and 28 mm base metal thicknesses, the 28 mm side of the test coupon was tapered 3 to 1, making the
thickness at the weld 9 mm. Is the WPS qualified for the two thicknesses?

Reply (2): No.

Question: A 3/8 in. thick SA-240 plate is used as base metal in coupon preparation. Actual base metal coupon thickness is 0.413 in., which
complies with thickness tolerances outlined in SA-480. Is the range of base metal thickness qualified 1/16 in. to 3/4 in. inclusive?

Reply: Yes, provided 3/8 in. is recorded on the PQR.

Question : According to WQ-407.9 for welding overlay SS on F22 material, we qualified with PWHT 14 hrs. on production welding is't possible to conduct PWHT with 6.8 hrs ? according to thickness is 12.5 inch. this a essential variable to change the PWHT time according to this code ?
