Zoref

Zoref, spelled צורף in Hebrew and pronounced Tzo-ref, though the typical American pronunciation is with a Z, means "Goldsmith" in both Biblical and Modern Hebrew, Zoref does not necessarily connote working only with gold; rather, it is a metalsmith that works with any kind of metallic substance.

Zoref, or Tso-ref comes from the Hebrew root צרף (Ts, R, F) which means attach, join, join together. In fact, Zoref literally means "attach," as a goldsmith literally attaches pieces of metals together.
