Ladies and Gentlemen,
Real time situation and answer done as follows.
Reference underwater welding use. Having been in the New York City construction scene for forty years, having patent in and having done underwater welding for thirty five years I have inputted on it use in New York City projects. I cannot find a clear reference to it use with the originator of our welding manual “NYSSCM” NYSDOT but if they were contacted they might have such. Have done NYCDOT contracts from various prospectives. I am aware of contract language, the New York State Steel Construction Manual and/or applicable industry standards / specification / codes. In many case we have accepted on less critical work
D1.1/D1.1M: 2010 (2ND EDITION) STRUCTURAL WELDING CODE-STEEL NEW 5 YEAR REVISION CYCLE (2010)
And as required
D1.3: STRUCTURAL WELDING CODE-SHEET STEEL
D1.6/D1.6M:2007 STRUCTURAL WELDING CODE - STAINLESS STEEL (2007)
In the case of wet underwater welding especial
“$100.00 D3.6M:2010 Underwater Welding Code
(2010)
This specification covers the requirements for welding structures or components under the surface of water. It includes welding in both dry and wet environments. “ is suggested.
If it is a critical weld having me or other with similar qualifications interacting is suggested. Fast answer is WPQR done in same water condition by the diver welder is a way in which the contractor could proof it will meet specified limits. Standing by.
Know there are better answers. Your views appreciated. I hope this helpful.
Sincerely
Len Andersen weld@spemail.org
