Buttering Question (ASME Section IX)
Buttering Question (ASME Section IX)
(OP)
I have welding procedure of 4130 base metal that was buttered with an A No. 1 filler metal before welding to a stainless steel plate. Can I use a buttering portion of this qualified procedure to perform a production weld repair on 4130 material?
