In 1983, Commission II of the International Institute of Welding initiated an effort to review and examine the role of nitrogen in steel weld metals. The objective was to compile in one source, for future reference, the available information on how nitrogen enters weld metals produced by various arc welding processes, what forms it takes in these welds, and how it affects weld metal properties.
This WRC Bulletin contains 13 reports and several hundred references related to Nitrogen in Weld Metals that show the importance nitrogen has in determining weld metal properties. Nitrogen is often (but not always) detrimental to the properties of carbon-manganese and low alloy steel weld metals, but the opposite is often true in stainless steels and their weld metals. Nitrogen has become a deliberately added alloying element in some newer stainless steels because it can enhance strength, corrosion resistance, and resistance to precipitation of certain undesirable phases in austenitic and duplex austenitic-ferritic stainless steels. Nitrogen also has a strong effect on the phase balance in austenitic and duplex weld metals. Publication of this WRC Bulletin - WRC Bulletin No. 369 was sponsored by the Welding Research Council, Inc.
