Re: [MW:10782] Voltage for GTAW electrode 2.4mm and 3.2mm

Do you want to run pqr?
if yes, first of all, please have heat input. Heat input is expressed in the formula; H=60EI/1000S. Where H is heat input (kJ/in or kJ/mm), E is arc voltage (volts), I is current (amps), S is travel speed (in/min or mm/min).
if you want to develop a procedure (WPS), just write what pqr said.

You can have the voltage range by doing mock up test. Then record the voltage reading[min,max] during the run. Make sure your welding machine ang other equipment in place.

Dear sir.

               

                What is the voltage range qualified for the GTAW electrode 2.4mm with an amp range 120-175 and 3.2mm with an amp range 150-220?

I can't find it in the standard code. I need this for my pWPS..
