BondCheck from Baugh&Weedon
The new BondCheck is a multi-mode bond-testing flaw detector that delivers rapid bond inspection in pitch-catch or resonance modes, or Mechanical Impedance Analysis (MIA), with outstanding defect sensitivity.
Typical inspection applications include carbon-fibre and metallic honeycomb structures that must be examined for delaminations, disbonds and core damage, as well as detection of small flaws and dry coupling. BondCheck is ideal for the broad spectrum of advanced-materials NDT demanded in the aerospace, automotive, wind-energy and advanced-manufacturing sectors.
Advantages of BondCheck include:
- Choice of probe types available for different inspections
- Flip function for left- or right-handed users
Overview
Housed in a lightweight instrument (1.2 kg) with a common user interface across the three modes, BondCheck offers simple, intuitive operator-driven set-up. The large daylight-readable screen gives the operator excellent data presentation and signal resolution. Users can configure colour schemes and employ a secondary panel to create a split screen with X-Y spot, frequency sweep, RF waveform or spectrum views—making BondCheck a versatile asset for laboratory or field inspection.
The BondCheck Pitch-Catch probe delivers high performance and durability. Ergonomic design provides robust, comfortable operation. Probe foot position can be adjusted by the operator to suit the task, and the hard-wearing probe tips are interchangeable; both rounded and flat tip profiles are available. The probe is broadband and suitable for a wide variety of applications.
BondCheck Resonance probes are offered in a range of frequencies (80, 100, 160, 200, 250 and 350 kHz) and can also be supplied as a multi-probe kit. Both probe types include an alarm LED and digital ID for ease of use; settings can be stored, and “air calibration” is possible to establish the most sensitive inspection frequencies.
The MIA technique is particularly valuable for detecting small defects, using a dry-coupled probe with a small contact area. It offers excellent near-surface defect sensitivity and is especially suitable for detecting skin-to-core disbonds in composite and metallic honeycomb structures.
