Nitinol Shape Setting & Micro-Welding

Thermal processing and joining of nitinol components.

Best Fit For:Engineers developing complex nitinol assemblies.

Capability Highlights

Program Metric	Typical Range	Procurement Value
AF Temperature	Custom per application	Controls deployment behavior in vivo.
Shape-setting inputs	Fixture geometry, target angle, cycle requirement	Reduces spring-back surprises during prototype validation.
Joining review	Nitinol, stainless, and dissimilar-metal feasibility	Aligns weld pull strength and HAZ expectations before build.

Decision Factor	Confirm Before Quote	Buyer Impact
Functional temperature	Af target, use temperature, superelastic or shape-memory mode, and tolerance band.	Keeps heat treatment tied to device behavior rather than only geometry.
Fixture and shape target	Mandrel, forming fixture, target angle, spring-back allowance, and cycle expectation.	Reduces iteration count when setting bends, baskets, snares, or complex tube shapes.
Weld interface	Material pair, weld location, pull strength, HAZ limit, and post-weld inspection.	Prevents joining assumptions from undermining nitinol performance.

Shape spring-back: Iterative tooling and heat treatment optimization.
Weld heat affecting nitinol behavior: Define weld location, pull-strength expectation, heat input limit, and post-weld inspection before joining.

Function and material review: Confirm nitinol grade, Af target, shape-memory requirement, joining materials, and inspection scope.
Fixture planning: Design or review forming fixtures, mandrels, weld support, and datum references for the part.
Thermal or welding process: Run shape setting or micro-welding with controlled heat input and part handling.
Functional release: Inspect shape, dimensions, surface condition, weld area, and transformation evidence when requested.

Yes, using specialized micro-welding techniques.

Af target, fixture design, heat-treatment profile, material lot, surface state, and post-process inspection all affect repeatability.
