PWHT @650 deg. cel and soaking time depending on the hardness requirements  if any.

Dear All, Thank you for your time to read my question.   I have to weld grade AISI 4130 with AISI 4140. Weld joint configuration is a groove weld 6inch dia.   Which electrode is suitable for welding these base metals together.   UTS of these parent metals is around 95 to110 ksi.   Thanks   Mhaskar Aly
