PQR:FORM QW-483

This presentation is to help you understand

the variables on the PQR form QW-483

As you review this presentation ,make sure

you have a printed copy of your QW-483

form .The idea is that as you look at eachslide, you look at the corresponding area on

your QW-483 form

NE

For this PQR form ,there are fewer differences in the classification of the

variables between the SMAW,GTAW.GMAW and SAW processes than

there were for the WPS form QW-482

The text colour shows whether anentry on the form (for

SMAW,GTAW,GMAW or SAW)

is an essential,supplementary or

non-essential variable

ResultType and Figure No

Types of bend will normally be transverse side, transverse root or transverse face bends.

QW-462.2 contains details of side bends

QW462.3(a) contains details of face bends and root bends

QW-163 contains the acceptance criteria for bend tests

Table QW-451.1 gives types and number of transverse bend tests required for base material thickness.
