Welding current on PQR for pulsed welding
Welding current on PQR for pulsed welding
(OP)
If pulsed welding is used for GTAW, such as 170A/70A (170 is peak and 70A is background current) is the min pulsed current and 300A/250A is the max pulsed current used for PQR test coupon, what current range should be put on the PQR if the code is per ASME SEC IX? 170-300A or 70-300A? or Calculating the average of the current range used and put on the PQR?
