To examine the feasibility of thermographic nondestructive testing of wood adhesive joints, several samples with starved joints, 10-50 mm square, were prepared using wood plates 1.3-3 mm thick of white seraya and urea-formaldehyde resin, and their thermal images were obtained with a thermographic device during heating by incandescent lamps and natural cooling. Surface temperatures were always more in an area of a starved joints than in other parts, and the poor joints were clearly visible in the thermal images.
