Abstract

A method for checking a joint between plastic details (1, 2) which are joined together by means of welding. A thermography technique is used wherein thermal radiation from the plastic details is observed in an area around the joint during production, by means of at least one camera (3) such as a digital infrared camera. The observed thermal image is compared with at least one reference value by computing means, whereby it may be established whether the fusion of the plastic details is adequate and of a sufficient quality. The thermal radiation is observed after heating and before joining of the plastic details, during cooling of the welded parts, or after cooling of the joint, when further heating is supplied to the formed joint by other irradiation means such as a lamp. The joint can also be thermographically imaged whilst under a mechanical load.
