Abstract: The process of inspecting welds done in production at Volvo Aero in Trollhättan is timeconsuming and a lot of this time goes into examining faulty objects. The aim of this thesis is to startdevelopment of a system that analyses acoustic emission from cooling welds to determine the qualityof the weld. Our aim is to be able to detect cracks in the material and to give information on thecracks using the data gathered by our sensors. To do this we will use methods to locate sound sourcesand then rate our findings and do some simplifications on the result of our calculations. We willanalyze our calculated data to find crack signatures and classify our findings and give alarms if wefind cracks that are considered too big for comfort. We will also give insight in to future aspects of ourwork and look at ways to improve on our proposed methods. We will discuss our systems pros, consand what things have been taken into consideration during design, and what strategies we proposeto handle the results from the system.
