This pre and post heat is need and takes over 24 hours to perform each process. The quick quenching of the weld is not desirable.
Dry atmosphere welding has been around for 40 odd years so how can the nepsys change these proceedures overnight.
If I knew anything about current nepsys job I certainly would not divulge any information on a public forum. All I am doing is letting you know it is more than just pumping out water and go welding.
