Medical Device Laser Welding

Microscale medical devices are built on components fused into clean, defect-free surfaces. TE uses tight process controls and practices during the laser welding process to minimize biocompatibility issues for medical applications. Our lasers can be positioned into tight geometry for contact-free, fast, repeatable welds with minimal heat-affected zones around joint sites. We use no fillers when welding similar and dissimilar materials that are used for:

• Proximal shaft assemblies (hypotube to wire weld) 
• Guidewires (coil to coil and coil to ground wire) 
• Torque cables 
• Catheter tips  
• Tube assemblies 
• Wire ball forming 
• And many other medical components

Our laser welding process supports hermetic environments, helically-oriented coils, lap and butt configurations, and more. Materials include:

• Stainless steels: 304, 316, 17-4, 420, 302, 303 and others 
• Nitinol, platinum and platinum alloys, and titanium 
• ELGILOY™ alloy, nichrome, INVAR™ alloy, MP35N™ and L605 

TE uses high-precision lasers for weld walls as thin as 0.002” (0,00508 cm) with laser spot sizes as small as 0.004” (0.0102 cm).  TE supports high volume welding of medical components, welding over ¼ of a million parts every week across our network of sites, including multiple automated lines welding 80’000 units each per week.
