Description and Applications: ER70S-2 is used primarily for single-pass welding of killed, semi-killed, and rimmed steels, but may also be used for some multi pass applications. Because of the added deoxidants, ER70S-2 can be used for welding steels that have a rusty or dirty surface, with a possible sacrifice of weld quality depending on the condition of the surface. Typical specifications for these steels are ASTM A36, A285-C, A515-55 and A516-70.
