Bring real-time intelligence to every weld on the line with Vision AI for weld inspection for medical devices. Built for the operations where one missed hermetic seal pinhole, undetected pore in a laser weld, or weak ultrasonic bond on a catheter hub can mean a recall, an FDA warning letter, or harm to a patient during a life-critical procedure. Whether you're inspecting laser welds on pacemaker titanium cans and stent struts, ultrasonic welds on catheter hubs and plastic housings, resistance welds on lead wires and electrodes, or laser welds on guide wires and marker bands, Roboflow extends your QC coverage to every weld on the line, validatable under FDA 21 CFR Part 820, ISO 13485, and EU MDR.
Hermetic Seal and Implantable Device Weld Inspection:
- Inspect titanium can welds on pacemakers, ICDs, and neurostimulators for porosity, cracks, and incomplete fusion
- Verify header port welds, lead wire connections, and battery enclosure seams before final hermetic helium leak test
- Catch surface defects, spatter, and heat-affected zone discoloration on cobalt-chromium and titanium implant welds
Laser and Resistance Welds on Catheters, Stents, and Wires:
- Inspect laser welds on stent strut connections, radiopaque marker bands, and guide wire terminations
- Verify resistance welds on electrophysiology catheter electrodes, lead wire joints, and ablation tip connections
- Catch subtle weld bead geometry deviations, undercut, and lack of penetration on sub-millimeter micro-welds
Ultrasonic and Plastic Welds on Combination Products and Devices:
- Verify ultrasonic welds on catheter hubs, luer connectors, IV set components, and insulin pen mechanisms
- Inspect plastic weld lines on PD solution bags, filter housings, blood lines, and drug delivery device assemblies
- Maintain a validated audit trail of weld inspection results for FDA 21 CFR Part 11 electronic records
Bring intelligence to every weld today. Stop defects from becoming recalls, warning letters, or harm to patients in life-critical therapy.
Frequently asked questions
What is weld inspection for medical devices with Vision AI?
Weld inspection for medical devices with Vision AI uses computer vision models to inspect laser welds, resistance welds, ultrasonic welds, and hermetic seal welds across pacemakers, ICDs, neurostimulators, catheters, stents, guide wires, drug delivery devices, and plastic medical assemblies. The system extends QC coverage to every weld on the line, catching porosity, cracks, lack of fusion, undercut, spatter, geometry deviations, and bond strength indicators that vary lot to lot. Medical device manufacturers use it to cut scrap, protect first-pass yield, and document compliance under FDA Part 820, ISO 13485, and EU MDR.
Can Vision AI inspect hermetic seal welds on pacemakers and implantable devices?
Yes. Hermetic seal welds are among the highest-stakes inspection tasks in medical device manufacturing. A single pinhole or incomplete fusion in a titanium pacemaker can-weld can let body fluids reach the battery and circuitry, causing device failure inside a patient years after implant. Roboflow models can be trained on your specific titanium laser welding acceptance criteria, including porosity, lack of fusion, weld bead geometry, heat-affected zone discoloration, and surface defects on cobalt-chromium and titanium can welds. The system extends 100% inspection coverage across every can weld coming off the line, with edge-optimized models that flag suspect welds for quality engineer adjudication before final helium leak test.
Does weld inspection for medical devices support FDA Part 820, ISO 13485, and AWS D17.1 acceptance criteria?
Yes. Roboflow models can be trained against your specific FDA 21 CFR Part 820 (Quality System Regulation for medical devices), ISO 13485 (medical devices quality management), and AWS D17.1 (specification for fusion welding for aerospace applications, also widely applied to medical device laser and resistance welding) inspection criteria. The system also supports AWS D16.1 robotic and automatic welding standards where applicable. It produces a validated inspection record for every weld that supports your FDA Part 820 design history file, EU MDR technical documentation, and ISO 13485 quality system audits. Your welding engineering and quality teams own the acceptance criteria; Roboflow provides the inspection engine that enforces them at line speed.
Can it integrate with our laser welding cells, eQMS, and validation workflow?
Yes. Roboflow Inference exposes a standard API and supports common industrial and life sciences protocols, so Vision AI weld inspection events flow into your existing laser welding cells, MES, eQMS, ERP, and validation workflow. Customers integrate with MasterControl, Veeva Vault QMS, Sparta TrackWise, and custom eQMS platforms through REST, MQTT, OPC UA, and direct database writes, with PLC-level integration to laser welding heads (Trumpf, Coherent, IPG Photonics), resistance weld controllers, ultrasonic weld stacks (Branson, Herrmann), and assembly cells where pass/fail decisions need to drive line behavior. Models are designed to be validatable under FDA 21 CFR Part 11, with audit trails for training data, model versions, and inspection results that support IQ/OQ/PQ documentation. Hardware fits ISO 14644 cleanroom environments, and Roboflow's field engineering team helps you select cameras that meet your cleanroom classification and the optical demands of micro-weld, hermetic seal, and ultrasonic bond inspection.
