agglomerated flux welding, submerged arc welding process, and welded joint resulting from a welding process

摘要

One or more techniques and / or systems are disclosed for a soldered agglomerate flux which may comprise (values expressed in% flux weight): 25 to 35% mgo, 20 to 28% coffee 2, 15 to 22% al 2 o 3, 12 to 17% sodium 2, and 0.2 to 0.4% carbon (% by weight). carbon may be introduced using at least one metal compound contained in the stream. A process for submerged arc welding of at least one workpiece made of austenitic stainless steel using the described flux is further disclosed. Also disclosed is a welded joint which may comprise 17 to 20% cr, 5 to 8.5% min, and 14 to 18% ni, which may be obtained using the process described.
