scope:

PURPOSE

This John C. Stennis Space Center (SSC) standard (SSTD) provides for a qualified American Welding Society (AWS) weld procedure for Flux Cored Arc Welding (FCAW) of carbon steel (Group 1 or 2). This weld procedure is applicable to welding of carbon steel plate of 1/8-inch to unlimited thickness and pipe of nominal 24-inch diameter and larger with wall thickness of 1/8-inch and greater for structural use at SSC.

APPLICABILITY

a. This SSTD applies to all contractor and subcontractor personnel involved with the FCAW welding of (Group 1 or 2) carbon steel plate and pipe for structural use at SSC.

b. This SSTD is also valid for welding of (Group 1 or 2) carbon steel to (Group 1 or 2) carbon steel pipe, tube, fittings, or plate used in fluid services, provided that the produced welds are not fluid pressure boundary or pressure containing welds; e.g., carbon steel pipe supports or doubler plates welded to outer walls of carbon steel pipe and fittings being an allowed application of this standard.
