evelrod I totally agree with you ,the vendor offered to change E7018 with E6013 with preheating in return, however all WPSs reguire all thickness in excess of 20 mm be preheated. As you know one of the purposes of preheating is to reduce Stress after welding so I can't detect the residual stress...
