Re: [MW:24106] PQR position conflicts

DEAR PRAKASH SIR,

                                 QW203 SAYS WPS QUALIFY IN ANY POSITION QUALIFIES PROCEDURE FOR ALL POSITION AND QW405.2 SAYS CHANGE FROM ANY POSITION TO VERTICAL UP. VERTICAL UPHILL PROGRESSION QUALIFIES ALL POSITION. MEANS IF MY WPS IS QUALIFY FOR 1G THEN IT QUALIFIES ALL POSITION OR NOT? AND IF THERE IS PWHT OR IMPACT REQUIREMENT THEN WHAT'S THE LIMIT? PLEASE HELP ME TO UNDERSTAND.

Hi!

As per ASME code

I) If PQR is qualified in 3G having Impact test requirement  for equipment  in such case you can qualify welder for any position based on this relevant PQR and WPS as per requirement

(For Impact test requirement  Welding position is essential for PQRi.e. 3G)

ii) If PQR is qualified for Non Impact test requirement(Even in 1G position ) in such case you require to qualify welder in any position as per requirement
