The paper presents the results of research on the characteristics of acoustic noise during friction stir welding (FSW) of aluminium alloys 1460 (Al-Cu-Li) and 1201 (Al-Cu) in order to create recommendations for improving sanitary and hygienic characteristics at the welder’s workplace. It was established that the noise level at the workplace during FSW with a tool rotation frequency of 1420 rpm is 83.3 ± 1 dBA for 1460 alloy and 80.2 ± 1 dBA for 1201 alloy. The use of special methods and means of protection against noise is recommended. 9 Ref., 4 Tabl., 2 Fig.
Keywords: aluminium alloys 1460 and 1201, friction stir welding, occupational safety, acoustic noise level, noise protection
