Laser beam welding of copper using visible laser radiation and beam shaping

Use of copper in mobility due to high thermal and electrical conductivity



highest seam quality for increased weld depth (e > 1,5 mm) in copper/ copper alloys



adapted intensity distribution to increase energy input and affect melt pool shape close to the surface

  • Buffering of keyhole instabilities

  • Increased weld seam quality
