Device evaluation of quality of weld seams by recording the temperature profile of the molten metal is cooled during welding.

摘要

Device for evaluating the quality of weld seams (2) for detecting the temperature profile of the molten metal being cooled during welding, characterized in that a detector head (4) can be placed fixedly on a welding torch (5) in direct proximity of the nozzle, so that a hole collimator (15) located there is transversely aligned to the weld bead (2) and a defined number of holes with tubes (18) of the collimator holes (15) that connect there are positioned perpendicularly above the molten metal being cooled, the weld (2), and each tube (18) of the hole collimator (15) is assigned an infrared receiver (19) being functionally connected all infrared receivers (19) with an electronic unit (8) and the electronic unit (8) in turn corresponds to an evaluation computer (10).
