Laser Welding

HIGH PRECISION. HIGH QUALITY.

Norman Noble has dedicated engineering resources and process development centers for producing rapid prototypes.

Norman Noble nitinol welding

UNIQUE LASER WELDING TECHNOLOGIES

Special welding processes are required to join together dissimilar materials for medtech implants. At Norman Noble, our process development team has developed unique welding technologies to weld exotic-grade metals and many types of dissimilar materials. This is especially effective for thin-walled, tubular medical components. No filler materials are used in Norman Noble’s laser welding processes, which are conducted using inert gases.

FACTS AT A GLANCE

  • Nitinol to nitinol welding
  • Welding of dissimilar materials
  • Spot and seam welding
  • Cross-Section SEM analysis for weld penetration depth
  • Can close gaps up to .008” wide with repeatable results
  • Process validation

LATEST WELDING TECHNOLOGY

  • Norman Noble’s latest welding technology is a 150W CW/1500W pulsed Fiber Laser with 4 axis motion plus servo-controlled beam tilt.
  • The system has live video imaging, an integrated wobble head, a programmable automated vision system, beam to crosshair alignment calibration, and a built-in laser power meter, which is extremely beneficial on validated processes.

NITINOL TO NITINOL WELDING

  • Norman Noble’s nitinol welding technologies allow for precise manufacturing of micro implant designs that require nitinol to nitinol welding.

TESTED & VALIDATED

  • Laser spot welding and seam welding can be tested using tensile tests, torque tests or cross sectioning for penetration confirmation.
  • Our laser welding medical device services are offered as a validated process.
