摘要
The method involves detecting the temp. of a measurement region with a fixed geometric relationship to the weld point using a first pyrometer (Py2), simultaneously measuring the temp. of measurement regions (6,7) on both sides of the weld seam (3), with a fixed relationship to the weld seam and influenced by the welding heat with further pyrometers (Py1, Py3) and detecting faults by comparison with desired values and temp. characteristics for sound seams. An Independent claim is also included for a measurement arrangement for on-line testing of quality of rolled weld seams for joined sheets.
