Micro-Welding Solutions for the Medical Device Industry 

Medical device welding presents distinct metallurgical and process control challenges due to the sensitivity of implantable-grade alloys, tight dimensional tolerances, and stringent cleanliness requirements. At Microtech Welding Corp., we offer over 25 years of specialized experience in precision micro-welding, providing advanced joining solutions using Micro-TIG (GTAW) and Laser Beam Welding (LBW) for Class I, II, and III medical components. 

Our facility is equipped to handle the welding of thin-walled geometries, thermally sensitive components, and critical structural joints, all within a clean, controlled processing environment compliant with ISO 13485 standards. 

Process Expertise in Medical Micro-Welding 

Micro-welding is the ultimate joining solution for high-precision medical devices due to its ability to:

• Minimize heat-affected zones (HAZ), reducing grain growth and distortion 

• Achieve weld bead sizes below 0.005”  with micron-level control 

• Maintain biocompatibility through inert gas shielding and contamination-free processes 

• Join dissimilar metals without compromising joint strength or corrosion resistance 

• Accommodate high aspect ratio weld geometries and constrained access zones 

Our welding services are engineered to provide full penetration where required, maintain structural integrity, and eliminate the potential for inclusions or porosity. 

Material Expertise for Medical Devices 

We routinely weld medical-grade materials compliant with ASTM F136, F138, and ISO 5832 standards, including: 

• Titanium – High strength-to-weight ratio, excellent corrosion resistance, biocompatible 

• Cobalt Alloys – High wear resistance, often used in articulating joint implants 

• Stainless Steel – Low-carbon, vacuum-melted stainless for implant applications 

• Additively Manufactured Materials – Post-processed 3D-grown alloys with unique surface structures 

We can also weld dissimilar material combinations and address thermal expansion differentials, using controlled ramp rates and custom fixturing. 

Controlled Environment & Quality Systems 

All welding is performed in lab-grade environments designed to reduce contamination and maintain repeatable process conditions. Our ISO 13485 Quality Management System  governs all aspects of welding procedure qualification (WPS), operator certification, traceability, and documentation.

 

• Laser Beam Welding (LBW): For ultra-precise welds in confined geometries, minimal HAZ 

• Micro-TIG (GTAW): Ideal for thin materials and dissimilar metal joints 

• CNC-Controlled Weld Sequences: Ensuring positional accuracy and repeatability 

• High-Resolution Optics and Vision Systems: For precise joint tracking and operator control 

• Vacuum and Inert Gas Chambers (Optional): For oxide-sensitive alloys 

Applications in the Medical Industry 

• Orthopedic implants – femoral stems, spinal cages, trauma plates 

• Surgical instruments – forceps, reamers, guide pins, end effectors 

• Cardiovascular devices – stents, wire guides, vascular clips 

• Robotic-assisted surgical tools – requiring miniature, high-strength welds
