ER308 welding wire, which is an austenitic stainless steel, typically has good resistance to galvanic corrosion when paired with similar metals. That said, it may be prone to galvanic corrosion when joined with dissimilar metals in the presence of an electrolyte. Minimizing this risk requires thoughtful selection of compatible materials along with suitable design considerations.
