Filler Metal
Filler metal is the material welders use to join two pieces of metal together. It's like glue, but for metal work. When welders mention filler metal in their resume, they're talking about the various materials (usually wire or rods) they add to create strong connections between metal pieces. This can include different types like stick welding rods, MIG wire, or TIG rods. Understanding filler metal selection and use is a key skill in welding because choosing the wrong type can result in weak or failed welds.
