4  Energy is transferred by laser or electron beam  Melted material creates weld joint after cooling down  Weld is narrow, additional material is not necessary  Welding is usually done under protective gas

5  Beam focusing to point of 1 mm diameter will heat it up to 20.000 °C  Depth of weld depends on beam’s diameter speed of feed and laser efficiency

6

7  Welds all weld-able materials  High speed  Narrow welding width  Small temperature deformation  High tensile strength  Velké investiční náklady  Odstínění pracoviště proti uniknutí laserového paprsku

9  Electron beam achieves narrower and deeper welds  It is an advantage to weld layer melt able metals (high melting temperature)  Alloys covered by layer of difficult melt able oxide (aluminum)  Field of using – aircraft building

10  Welding of difficult weld able metals, for example: titanium and its alloys  High precision of beam’s guidance and high weld strength

11  High investment and operation costs  Difficult preparation of welding parts  Necessity of work place shielding against roentgen radiation

12  What are the advantages of electron beam welding?
