EBW is used for joining ferrous metals, light metals, and precious metals and their alloys to themselves, or to each other, eg. aluminium, nickel, copper, stainless steel, platinum, titanium, tungsten, tantalum.
Typical applications include aerospace, automotive, marine and integrated electronics. The low heat input means that, for example, internally mounted, heat sensitive electronic packages may be sealed in a welded enclosure without damage.
