Grade 2 Titanium Foil Processing: Rolling, Slitting and Welding
- Gr2 titanium foil
Grade 2 titanium foil processing can include rolling, slitting, forming and joining. Each step changes or depends on the material condition, dimensions and surface. Equipment settings and achievable tolerances must be established for the actual product and order.
Material and purchasing requirements
Grade 2 is unalloyed titanium, UNS R50400. ASTM B265 covers annealed titanium strip, sheet and plate, including Grade 2. Confirm that the ordered foil form and thickness are covered by the contracted edition. Specify dimensions, tolerances, delivery condition, finish and the requested lot records.
Rolling and slitting
Cold rolling reduces thickness and can change material condition and formability. Intermediate treatment, if required, must follow the approved process for the grade and product. Slitting requires control of tension, edge condition and dimensional acceptance; burrs or edge cracks can affect later forming and joining.
| Operation | Order-specific controls |
|---|---|
| Rolling | Incoming condition, target thickness, flatness and surface acceptance. |
| Slitting | Width, tolerance, edge quality and coil handling. |
| Forming | Geometry, rolling direction, tooling and representative trials. |
| Welding | Joint design, shielding, qualified procedure and inspection. |
Welding and inspection
Thin foil can be sensitive to heat input, fit-up and contamination. Select and qualify the welding process for thickness, joint design and required properties. Cleaning and suitable shielding must be addressed in the procedure. Weld color alone does not establish joint acceptance; use the inspection and tests specified for the application.
Weld strength, production speed and tolerances cannot be promised from generic parameters. For medical, aerospace or pressure applications, the finished part requires separate qualification under the applicable requirements.
Frequently asked questions
Can one welding setting be used for every foil thickness?
No. Validate the procedure for the material, thickness, joint and equipment.
Does a base-material certificate qualify the weld?
No. The joint and welding process require the specified verification.
