Welding Wire ESAB OK Autrod 12.64 SG3 G4Si1

ESAB OK Autrod 12.64 – Copper-Coated MAG Welding Wire for Structural Steel

The ESAB OK Autrod 12.64 is a universally applicable, copper-coated solid wire electrode for MAG welding of unalloyed and low-alloy steels. The wire is ideal for joint welding on general structural steels, pipeline steels, fine-grain structural steels, and in shipbuilding. Thanks to its reliable welding properties and very good mechanical characteristics, it is suitable for both manual applications and mechanized use on welding stations and robots.

The 4Si1 alloy ensures stable welding behavior, good wetting, and high seam quality. Under mixed gas, the OK Autrod 12.64 achieves very good toughness values down to -50 °C, making it suitable for more demanding constructions with increased impact strength requirements.
