Who Is Welding Wire?

A welding wire is a slim metallic rod that is ignited to generate a heated arc for the purpose of fusing metal pieces together (welding) by rendering the wire soft via hammering or compressing under an applied heat source.

What wire is used for welding?

An ER70S-6 solid wire is the most common choice for welding mild steel. This widely available wire is found in general fabrication, automotive welding applications and can be used for robotic welding, as well as to complete root passes for pipe welding and other critical or industrial applications.

What is welding wire made from?

Hard Wire. MIG welding wire is primarily made of base metal. It may also include manganese, titanium, and silicon (residue of which can often be seen after welding). The wire is typically coated in copper which in addition to helping reduce oxidization during welding, can prevent the wire from rusting too.
