Wps to Qualify - Welds With Buttering

Wps to Qualify - Welds With Buttering

Wps to Qualify - Welds With Buttering

(OP)
ASME IX - 2007

QW-283 Welds With Buttering
QW-283.1 Scope. This paragraph only applies when
the essential variables for the buttering process are different than the essential variables for the process used for subsequent completion of the joint. Common examples are:
(a) the buttered member is heat treated and the completed
weld is not heat treated after welding
(b) the filler metal used for buttering has a different
F-Number from that used for the subsequent completion
of the weld

QW-283.2 (...) If the buttering is done with filler metal of the same composition as the filler metal used to complete the weld, one weld test coupon may be used to qualify the dissimilar metal joint by welding the first member directly to the second member in accordance with Section IX.


The WPS to qualify is:
Nickel 625 Clad API 5L Pipe to
Nickel 625 Clad & Butter layer on 4130

The buttered member is heat treated and the completed
weld is not heat treated after welding. The filler metal used for buttering (ER-NiCrMo3) has a same F-Number from that used for the subsequent completion of the weld.


HOW DO I QUALIFY THIS WPS???
WHAT BASE MATERIALS QUALIFIED??
 

RE: Wps to Qualify - Welds With Buttering

Do you understand ASME B&PV Code, Section IX, since you quote excerpts above? Read Section IX Article II. Select your base metal grouping in Article IV for each and the filler metal F-No, and follow the rules. This will be a groove weld procedure qualification.
