摘要

Arrangement for non-destructive testing of thermographic joint connections, such as a resistor point welding compounds and material defects such as cracks in the components (2) by means of induction - thermography, with a miniaturized, which are to be operated with one hand hand test device (1) with a robust housing (3), in which a compact shaped test head (4) with one of a change test head system (5) replaceable inductor (6), a camera as bolometers within (7), a shielding (8) between the latter and the inductor (6), distance -, - function generator and temperature sensors, a above the within (7) in the housing (3) positioned fan (9) as well as manually actuatable operating elements (10) are integrated, and with a with the test head (4) of the hand test device (1), which may be mobile supply unit (13), which is a mess - and - control method according to the pc (14) with industry monitor (18) for the test display, an induction generator (15), which by means of a measuring program - of the measuring and control method according to the - pc (14) is to be driven, and a supply connection (16), by means of a supply cable (17) is to be connected to strongly current.
