Hi Everyone,
I have an older 2004 D1.1 which states in the Commentary section
C3.6 Limitation of WPS Variables
Although prequalified WPSs are exempt from tests,
the code does require that the Contractor prepare a written
WPS to be used in fabrication. This is a record of the
materials and the welding variables which shows that the
WPS meets the requirements for prequalified status.
It is the intent of the code that welders, welding operators,
tack welders, and inspection personnel have access
to the written prequalified WPS. The code requires that
four critical variables be specified on the written prequalified
WPS within limits that will insure that it provides
meaningful guidance to those who implement its provisions.
The allowable ranges for amperage, voltage, travel
speed, and shielding gas, as applicable, are the same as
those allowed for qualified WPSs in 4.7 of the code. The
limitation imposed on these four variables are sufficiently
conservative to allow rounding off.
Now when looking for this section in 2015 D1.1 Commentary it has been removed, Have they removed this completely from the code or moved it somewhere else?
