Procedure:
Use AC or DC reverse or straight polarity. Clean the weld area
Bevel breaks and cracks deep enough so the first pass ties in the bottom of the crack
In most cases, preheating is not necessary, but heavy sections should be preheated to approximately 400F
Use a short arc. Stringer beads are recommended
Skip or back-step weld and peen to relieve stresses.
Allow the casting to cool slowly
