Thickness range of Tee Joint (full penetration)

Thickness range of Tee Joint (full penetration)

Postby Hoangcsw » Sun Oct 18, 2015 6:29 am

Dear all,

According to ASME IX,
What is the thickness range of Tee Joint (double bevel)?
What is the thickness range of abutting member (groove member)?
What is the thickness range of non-butting member?

Could anyone help me to the above questions?
Thanks

Hoangcsw,
What to you mean by saying "abutting member" and "non-butting member"? Please clarify

Hoangcsw,
See below

Interpretation: IX-13-16
Subject: QW-202.4, Dissimilar Base Metal Thicknesses Date Issued: June 10, 2013 File: 13-635
Question: When employing a WPS to join flat plates of dissimilar thickness in a groove-weld tee joint, is it a requirement of QW-202.4 that both the thicker and thinner members must be qualified within the range permitted by QW-451 unless the alternative provided in QW-202.4 is used?
Reply: Yes.

QW-202.4 Dissimilar Base Metal Thicknesses. WPS qualified on groove welds shall be applicable for production welds between dissimilar base metal thicknesses provided:
(a) the thickness of the thinner member shall be within the range permitted by QW-451
(b) the thickness of the thicker member shall be as follows:
(1) For P‐No. 8, P‐No. 41, P‐No. 42, P‐No. 43, P‐No. 44, P‐No. 45, P‐No. 46, P‐No. 49, P‐No. 51, P‐No. 52, P‐No. 53, P‐No. 61, and P‐No. 62 metal, there shall be no limitation on the maximum thickness of the thicker production member in joints of similar P‐Number materials provided qualification was made on base metal having a thickness of 1/4 in. (6 mm) or greater.
(2) For all other metal, the thickness of the thicker member shall be within the range permitted by QW-451, except there need be no limitation on the maximum thickness of the thicker production member provided qualification was made on base metal having a thickness of 11/2 in. (38 mm) or more. More than one procedure qualification may be required to qualify for some dissimilar thickness combinations.

Hope that helps,
Cheers,
BB
