Micro Laser Welding

Micro Laser Welding

TRUSTED QUALITY CRAFTSMANSHIP & SUPERIOR TECHNOLOGY

While micro TIG welding is often less expensive, there are many applications where laser welding results in a superior outcome. For this reason, Micro Arc Welding has invested in developing one of the most technologically advanced laser welding facilities in the country for your tool and mold repairs.

Operating the most advanced laser equipment available for the micro welding industry, our team of Class A micro dimensional welders are able to place and form weld in complex shapes and sizes within specified tolerances while preventing, controlling and eliminating distortion often caused by the welding process. An extremely low-amp micro TIG welder and microscope give us the ability to use welding wire as small as 0.003″. In a field where precision is paramount, they have the manual dexterity, surgeon-like steadiness, patience, creativity, and artistic ability required to visualize and create complex, 3-D geometric shapes.

Micro Laser Welding Capabilities

  • Precision laser welding for microscopic and miniature components
  • Weld sizes as small as 0.001” (25 microns)
  • Minimal heat-affected zone (HAZ)
  • Excellent control for thin, delicate, or heat-sensitive parts
  • Capable of fusion welding and laser spot welding
  • Suitable for prototype, short-run, and production volumes
  • Repeatable results with tight tolerances
  • Ideal for cosmetic and structural micro welds

Advantages of Micro Laser Welding

  • Extremely high precision and accuracy
  • Low thermal input, reducing distortion and part damage
  • Minimal post-weld finishing required
  • Ability to weld very small or complex geometries
  • Non-contact process minimizes mechanical stress
  • Clean welds with excellent cosmetic appearance
  • Highly repeatable for production applications
  • Suitable for materials difficult to weld using conventional methods

Micro Laser Welding Applications

  • Joining miniature metal components
  • Repair of precision tools, molds, and dies
  • Medical device component welding
  • Electronics and micro-electronics assembly
  • Aerospace and defense component repair
  • Sensor and connector welding
