Abstract: The invention relates to a device and a method for process monitoring in a deposition welding method. The object of the invention is to provide a device in which the process monitoring in a deposition welding method is further optimized, and process deviations that can affect the quality of a product are reliably avoided. Surprisingly, the devices known in the state of the art for process monitoring in deposition welding can be developed to a substantially optimized process monitoring, in which said devices are supplemented by equipment for detecting a time period during which the detected surface region is greater than a predetermined minimum value, and equipment for discontinuing the deposition welding process in an automated manner in the event that the time period of the detected surface region is greater than a predetermined time value.

Abstract: A deposition welding process monitoring device that includes an optical detector (10), a conversion unit (70) and an evaluation unit (60) with equipment (60a) configured to determine a monitoring region (61a) of an image (61), equipment (60b) configured to repeatedly detect a surface region (61b) of the monitoring region (61a) in which a temperature-dependent intensity distribution exceeds a specified minimum value (62), equipment (60c) configured to detect a time period (61c) during which the detected surface region (61b) in which the temperature-dependent intensity distribution exceeds the specified minimum value (62) is greater than a specified limit value (63), and equipment (60d) configured to discontinue the deposition welding process if the time period (61c), during which the detected surface region (61b) in which the temperature-dependent intensity distribution is greater than the specified limit value (63), is greater than a specified time value (64).
