Charmant’s laser micro welding technology successfully eliminates deterioration of material or mechanical characteristics cased by thermal effect in conventional brazing.

Laser micro welding vs Conventional brazing

Conventional brazing

Conventional brazing

  • Large area is thermal affected to cause deterioration.
  • Limits the dimensions for quality welding
  • Likely to cause scratches and deformatons

Laser micro welding

Laser micro welding

  • Minimal thermal affect causes little degeneration of strength
  • Accurate welding in microscopic dimensions
  • No scratches and deformations

CHARMANT instruments are As Laser micro welding, which requires rather accurate finish of components microscopic oimeusions .
