Jul 06, 2020 · Which welding rod is the best for welding (SMAW) ASTM A128 grade manganese wear plate (45mm) for crushing equipment between stainless steel rod (E312-16) and Low Hydrogen welding rod joining Armox plate ( lighting) 16mm and why? Reply. Leave a Comment Cancel reply. Comment. Welding Precautions for T-1 Steels - lincolnelectricWhat precautions should I take when welding T-1 steels? T-1 is a quenched and tempered steel. Welding quenched and tempered steels may be difficult due its high strength and hardenability. The base steel around the weld is rapidly being heated and cooled during welding, resulting in a heat affected zone (HAZ) with high hardness.
