[MW:16101] Dissimilar Base Metal Thicknesses ASME Section IX

Dear Experts,

I need ASME interpretation IX-86-43 for following query.

QW-202.4, Dissimilar Base Metal Thicknesses

Date Issued:     December 22, 2004

File No:            04-599

 

Background:  A procedure qualification test coupon using the same P-Number material and consisting of two plates of different thicknesses are welded together, where the thicker of the two plates (T2 = 1-1/2" thick) has been tapered on a 4:1 taper down to the thinner plate thickness (T1 = 1" thick).

 

Question (1):  Does this test coupon qualify the WPS for a base metal thickness range of 3/16" to 8"?

 

Reply (1):  See Interpretation IX-86-43, Question (2).



Thanks & Regards


Hiren Sevak
