| Abstract: | Non-destructive testing (NDT) of heat sealed capsule body cloth defect is the key issue in captive balloon production and needs to be resolved urgently. Through theoretical and experimental study of lock-in thermography, a NDT system of heat sealed capsule body cloth defect was proposed to identify and locate the defect automatically. According to phase difference, lock-in thermography NDT system can even effectively identify the type of heat sealing defects and presents high reliability and strong anti-jamming capability. This system can not only be used to identify the heat sealed capsule body cloth defect, but also be widely used in NDT of related materials or structures. |
