<p>A method is disclosed for establishing heat treatment of a weld or glue connection between two mutually adjacent surfaces of components, for instance tubes, using respectively an adhesive material, for instance plastic, more particularly epoxy resin. Heat is supplied around or close to the weld surfaces for connecting. In order to measure the correct quantity of supplied heat and prior to the heat supply, a test loop (10) is arranged around the weld. The loop is provided with a temperature-sensitive interrupter (13) and an electric fuse (14) connected in parallel thereto. A predetermined time after the interrupter has responded as a result of the correct temperature being reached, a current surge is passed through the safety fuse in the loop, so that it is possible to determine precisely whether the welding has been carried out for a sufficiently long time and with sufficient heat.</p> |
