ER70S-6 filler material can be used for which of the following processes?

ER70S-6 is a type of filler material that is primarily used for various welding processes due to its versatility and properties. It is designed to be used with both gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW).

In GMAW, the ER70S-6 wire is fed automatically through a welding gun and is melted by an electric arc to create a weld. This process is efficient for many applications, especially when speed and ease of use are important. The ER70S-6 filler material is known for its ability to provide good weld quality, mechanical properties, and increased impact toughness.

On the other hand, in GTAW, ER70S-6 can be used as a filler rod that the welder adds manually into the weld pool created by a non-consumable tungsten electrode. This method allows for high-quality joints and is often used when precise welds are necessary.

Thus, the choice pointing to GMAW or GTAW as the applicable processes for ER70S-6 filler material highlights its compatibility with multiple welding methods, making it a versatile option for welders dealing with carbon steel.
