Magnetic Almen Strip Holder
AMS 2590-compliant magnetic holder for quick, secure strip positioning during peening intensity measurement.
Magnetic Almen Strip Holder for Fast Flap Peening Intensity Checks
Place, peen, measure no tools required. This magnetic holder secures an Almen strip directly on ferrous parts so you can verify rotary flap peening intensity quickly during setup, rework, or audit checks. It's the practical companion to A-strips and an Almen gage for specification-driven processes.
Technical Data
- Type: Magnetic Almen strip holder for on-part intensity verification
- Strip format: SAE J442 Almen A-strips (76.1 x 18.95 mm)
- Standards: Supports flap peening processes; fulfills AMS 2590 practices
- Use with: Almen strips (Aero Plus or Industrial), Almen gage for arc-height measurement
- Mounting: Magnetic base for ferrous substrates; tool-free placement and removal
Recommended Use
- Setup and qualification of rotary flap peening parameters (RPM, exposure time, stand-off)
- Periodic intensity checks in production and MRO environments
- Audit documentation where on-part verification is required
How to Use
- Clean a flat ferrous area where the holder will sit; ensure stable contact.
- Seat the magnetic holder and install an Almen A-strip per your SOP.
- Peen the area using your specified flap size and verified RPM.
- Remove the strip and measure arc height with an Almen gage.
- Adjust RPM/exposure as needed and repeat until the target intensity is achieved.
- Record readings for your quality file or audit trail.
Frequently Asked Questions
Which strips should I use?
Use Almen A-strips per your process specification Aero Plus for tighter tolerances or Industrial grade for general use.
Does it work on non-ferrous parts?
The magnetic base needs a ferrous surface. For non-ferrous workpieces, use a bolt-on holder or attach a ferrous backing plate as allowed by your procedure.
Can I use it on curved surfaces?
Yes if the contact is stable and flat enough for repeatable seating. Otherwise, use a suitable fixture or flat pad to ensure consistent placement.
What else do I need to verify intensity?
An Almen gage to measure arc height, calibrated tachometer for RPM control, and the correct flap/mandrel combination defined by your procedure.
