Use of Low Hydrogen rods, such as E7018, and E8018, provides greater ductility. Those rods have been used with a high degree of success. In instances where pre-heat is not possible, use of a 309 Stainless Rod should be considered. Where higher tensile is required, a E10018 rod may be used with attention to the pre- and post- thermal treatment.
