What does ER70S-6 stand for?

Solid wire: An overview As an example, for a commonly used solid wire — AWS ER70S-6 — the “ER” indicates that the filler metal is an electrode or rod; the “70” signifies that it has a tensile strength of 70,000 pounds per square inch (psi); and the “S” means that it is a solid wire.

What is ER70S-6 welding wire?

Pinnacle Alloys ER70S-6 is a premium carbon steel electrode formulated for welding carbon steels with a yield strength range of 55,000-70,000 psi. Pinnacle Alloys ER70S-6 is well suited for steels containing medium to high levels of mill scale and mild amounts of contaminants.

Can you weld stainless steel with ER70S-6?

Use 75% Argon/25% CO2 for thinner steels. Use only argon for aluminum. You can use a triple-mix for stainless steels (Helium + Argon + CO2). Use ER70S-6 wire when more deoxidizers are needed for welding on dirty or rusty steel.

What is the difference between er70s2 and ER70S-6?

Both the wires can be used for similar jobs due to identical capabilities. The major difference between the two products is prominent when the user is operating on contaminated or rusted surfaces, in which case the ER70S6 provides better penetration and higher quality of welds.

What does the R stand for in welding?

R = rod; this means that it does not have to be an electrode to be used as weld metal.

What does the R mean in welding?

When a backing bar is used to achieve complete joint penetration, its symbol is placed across the reference line from the basic weld symbol. If the bar is to be removed after the weld is complete, an “R” is placed within the backing bar symbol.

What shielding gas is recommended for welding of aluminum?

Pure argon
Pure argon is the most popular shielding gas and is often used for both gas metal arc and gas tungsten arc welding of aluminum. Mixtures of argon and helium are probably the next common, and pure helium is generally only used for some specialized GTAW applications.

What do the letters and numbers mean in ER70S-6?

70 indicates in 1000 psi increments the minimum tensile strength of the weld metal produced by the electrode when tested according to the specification. In this case, 70 indicates 70,000 psi. S indicates that the filler metal wire is solid. 6 indicates the chemical composition of the solid filler metal wire.

Is ER70S-6 flux cored?

ER70S-6 – Solid core – MIG & Flux-Cored Welding Wire – Filler Metals – Welding – Products.

What can you weld with ER70S-6?

Type ER70S-6 is a wire with higher levels of Deoxidizers welding of steels with moderate amounts of scale or rust. (Mn & Si) compared to other carbon steel wires. This wire is suitable for welding of steels with moderate amounts of scale or rust.

What does the 70 stand for in ER70S 3?

welding rod
For example, ER70S-3 indicates an electrode or welding rod (ER) that will produce weld metal of a minimum 70,000 psi tensile strength (70); is a solid bare wire or welding rod (S); of a specific chemical composition (3) as shown in Figure 5.
