摘要: This paper presents the non-destructive testing of brazed joints between cooling tube and heat sink by infrared (IR) thermography, which is becoming a useful recognised technique to evaluate quality joints. A sensitive IR camera generates an image surface based on temperature each point sufficient overall thermal contact In steady state superconducting Tokamak (SST-1), plasma facing components (PFC) are actively cooled during operation. The tubes sink. used visualize transfer sink, enables identify significant faults in contact. Three-dimensional (3D) finite element (FE) analyses have been performed simulate brazing defects. experimental observations obtained from thermography confirmed FE simulations. Additional investigations such as X-ray images test section also observations.
