why do u want to qualify separately?

[Ramin Kondori]

It is better to prepare a but-weld test coupon.

Then weld it according to your WPS.

Remember to record all the parameters during welding.

Then send your coupon to lab and specify the standard and required tests (and conditions of tests like impact test temp).

Wait for the results.

When you receive the results if they are all accepted then fill out PQR form and receive all parties signatures as per your ITP.

If your tests have rejected sample, then you have to go for re-tests or prepare a new coupon with modified WPS and repeat all over again.

Good luck

sir i want to make it easy to those people who are fresher i know just make a wps of 6g position it will be done for all except what welding process we used

[steel_microbe]

QW-211 BASE METAL
The base metals may consist of either plate, pipe, or
other product forms. Qualification in plate also qualifies
for pipe welding and vice versa. The dimensions of the test
coupon shall be sufficient to provide the required test
specimens.

Groove-weld test qualifies for fillet welds for all thickness and diameters.

[Kannayeram Gnanapandithan]

As per ASME, for PQR, Test on Flat 1G will qualify all position if no impact requirements.  For WPQR, 6G will qualify all position. Let us be clear. In same way product form, for wps no restrictions but for welder it is restricted with limitations.
