Re: [MW:14421] range of welding parameter (CURRENT,VOLTAGE,TRAVEL SPEED,ETC.) for WPS from PQR.

Hi,
 
If Ur code of test is ASME-IX, then for an Example, refer QW-255 for FCAW Process , heat input is a Supplementary variable if U have Impact test, hence limit Ur parameters as per the variable table.
 
Then Current ,  Volt, travel speed are non Essential variable , if there is no Impact Test for Ur PQR.
 
In PQR U should right, what U observed the actual parameters and should weld as per the welding paramaters recommended for a partiuclar brand from the consumable manufacturer. And in WPS, it is purely based on Impact or Non Impact test conditions, U should refer Essential variable table .
 
If there is no impact test and also heat input is not an essential varaible, then U can refer to the consumable manufacturer's recommendation for welding parameters, for each size of electrodes or Fillers.
 
I think this is enough.......
 
Cheers,
Sarav
