ER70S dash X can be used for which welding processes?

The designation ER70S-X refers to a family of filler metals primarily used in GMAW (Gas Metal Arc Welding) and GTAW (Gas Tungsten Arc Welding) processes. This classification indicates the composition and the usability of the electrode, along with its ability to produce a weld deposit with specific mechanical properties and chemical compositions, particularly suited for various applications.

In the context of GMAW, these filler metals are supplied in the form of a spool of wire that feeds through a welding gun, allowing for continuous welding and a high level of control over the weld bead. Similarly, in GTAW, which is commonly known as TIG (Tungsten Inert Gas) welding, the ER70S-X fillers can be used in conjunction with a non-consumable tungsten electrode and a shielding gas, facilitating the creation of high-quality welds.

Both of these processes are widely adopted in industries requiring precise control over the weld and the ability to work with thinner materials without distortion. This versatility and the ability to achieve different weld profiles make ER70S-X a preferred choice for these methods. Thus, their suitability for GMAW and GTAW makes this option the correct one for identifying the processes compatible with ER70S-X filler metals.
