Dear Rahman,
Theres no rule to select the voltage.You can check the electrode manufacturers data sheet for the specific brand / size.
Dear experts plz correct me if I am wrong

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.
2011/4/22 <mus.hawa@yahoo.com> 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. Sent by Maxis from my BlackBerry® smartphone

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.. -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding+unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/ The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.
