Stronger joints using Esab rods

Practical benefits

Higher weld metal strength: You achieve durable and robust joints thanks to the increased silicon and manganese content.
Tolerant to surface impurities: You can weld smoothly even on steel with light rust or mill scale present.
Clean and uniform finish: The copper coating provides consistent melting and helps you create neat, sound weld seams.

In a nutshell

The right choise for

With the Esab ok Tigrod 12.64 tig welding rod, you create strong and reliable joints on non-alloyed and low-alloyed structural steels. Thanks to the increased manganese and silicon content, you can weld with low sensitivity to surface impurities like light rust or mill scale while achieving higher weld metal strength. The copper coating ensures smooth melting and a clean, uniform bead appearance. Featuring a diameter of 1.6 mm and a length of 1000 mm, this rod gives you precise control for pipe welding, sheet metal fabrication, and general metal construction. Used with pure argon shielding gas, it delivers sound, porosity-free results meeting ER70S-6 and W4Si1 specifications.

Product description

OK Tigrod 12.64 is a copper-coated TIG welding rod of the ER70S-6/W4Si1 type, designed for welding unalloyed and low-alloy carbon-manganese steels. Thanks to its higher silicon and manganese content compared to OK Tigrod 12.61, this welding rod offers greater strength and is less susceptible to surface contaminants such as light rust or mill scale. This results in a stable weld and a smooth weld appearance.

Copper-clad TIG welding rod for unalloyed and low-alloy steel
Classification AWS A5.18 ER70S-6 / EN ISO 636-A W4Si1
Higher silicon and manganese content for higher weld strength
Low sensitivity to surface contaminants
Produces smooth and clean welds
Suitable for general structural work, pressure vessels and shipbuilding
To be used with argon (I1) as a shielding gas

OK Tigrod 12.64 is used for TIG welding of structural steel, boiler and pressure vessel steel, in mechanical engineering and shipbuilding, where a reliable welded joint with good mechanical properties is required.
