E60 vs E70 welding electrodes
E60 vs E70 welding electrodes
(OP)
Our specs for welding structural steel (buildings) have historically called for the use of E70 electrodes. Recently a contractor has requested the use of E60 for some A36 material citing "matching strength criteria". A little research reveals this is not a new concept. What are other firms doing? Any reason not to allow this with the appropriate check of the weld design?

RE: E60 vs E70 welding electrodes
My concern would be consistency - is the entire job to be done with A36 steel and E60 electrodes? If higher strength steel/electrodes are required for other parts of the job then I would be inclined to say stick with the E70 everywhere so it doesn't get mixed up.
