Sammanfattning (abstract):
In the process of making welding wire an important step is to descale an oxide layer from the surface of the wire. If the oxide layer is not entirely removed it will affect the quality of the finished product. A common way of descaling is to use acids which is not quite environmental friendly. It is possible to mechanically descale the wire but the method needs to be better since the current methods does not give consistent results. In this work the possiblity to descale the wire using ultrasounds have been investigated. It has been theoretically analysed, modelled in MATLAB and compared with results from an existing mechanical wire descaler. The results have not been validated through experimental analysis. The results show that ultrasound may be an interesting technique to investigate further, and guidelines and important variables for future experiments are given.
