In Line Phased Array Inspection of Encapsulated Battery Structural Adhesives
Inline phased array testing maps structural adhesive wet-out and void formation through metal pack enclosures in real time at production line speeds.
EN 12668-1
Meaning
An ultrasonic test instrument standard dictates the performance requirements and verification procedures for apparatus used in manual non-destructive testing. The document en 12668-1 defines the electrical and mechanical characteristics of pulse-echo equipment, ensuring consistent results during the inspection of metallic components. Manufacturers must calibrate signal amplifiers, time-base accuracy, and transmitter pulses according to these specific parameters to validate equipment functionality before field use.
Performance Verification
Detailed testing protocols verify the equipment meets defined limits for linearity, frequency response, and noise levels. Calibrated electronic references assess the transmitter pulse shape and receiver gain stages to confirm signal integrity across the designated frequency range. Periodic assessments of these variables prevent measurement drift that might compromise the detection of internal flaws within welded structures or forged parts.
Design Specification
Electronic hardware layout influences how successfully the device adheres to the prescribed pulse-echo criteria. Stabilized voltage supplies and shielded internal circuitry minimize crosstalk between channels, which reduces signal interference in high-gain applications. Internal software logic manages the digitization of acoustic echoes, where sampling rates must exceed the Nyquist frequency to maintain waveform fidelity during processing.
Calibration Protocol
Systematic checking of the device against a known electronic simulator provides a secondary assurance of operational precision beyond the initial factory settings. Technical staff perform these verifications at regular intervals or after significant repairs to ensure the system remains within the tolerances required for safe industrial service. Adherence to these protocols establishes a baseline for comparability between different testing units, as valid measurements rely entirely on this shared technical foundation.
