The welding parameters recorded on the PQR are those actually used to weld the test coupon. In other words, there must be a witness to watch the meters to see what the amperage actually was and record it, likewise the witness records the actual arc voltage, travel speed, etc. All the values recorded have to be the actual values used while actually welding. This can not be accomplished by the welder unless he or she has eyes on the back of their head so they can see the meters while they are welding.
Most welders will utilize a rather narrow range of amperage and arc voltage when they weld the test coupon and those are the values to be recorded on the PQR. For instance, the welders amperage may vary between 135 and 145 amps using 1/8 inch diameter E7018 while the voltage may vary between 23 and 27 volts. Those are the values to be recorded. Likewise for the travel speed for individual weld beads. The travel speed may be 2.5 ipm for the root pass and 5 ipm for the second pass, then 4.3 ipm for the next and so on.
I record the preheat or interpass temperature, amperage, arc voltage, travel speed, etc. for each weld pass in a table at the end of the PQR. Then I list the high and low for each parameter on the PQR. I even include a sketch with the actual groove angle, actual root opening, etc. Then I show the approximate placement and relative thickness of each weld pass and the number of weld beads required to fill the groove. Again, we are discussing the information that is recorded on the PQR. I do not use the form or sample forms include in D1.1 or ASME Section IX. They don't do what I need them to do. I have developed my own forms that better suit my needs.
The welding parameters listed on the WPS can have greater range than that used by the welder when welding the coupon for the PQR. They should be reasonable in that the welder should be able to utilize the full range listed and produce acceptable welds. In other words an amperage range of 0 to 220 amps listed in the WPS is not reasonable for a 1/8 inch diameter E7018. It would be reasonable to list 120 to 150 amps for 1/8 inch diameter E7018 in the WPS. A quick word of caution, different codes have different requirements for the allowable range for each welding parameter, so check the specifics of your welding code.
I hope this addresses your concerns and helps you to better understand the information that is recorded on the PQR and what is listed on the WPS.
