摘要铜由于具有良好的导热性和较高的熔点，在电弧焊过程中通常需要预热处理以保持令人满意的熔深，因此被列为难焊材料。然而，与铝和镁一样，铜基本上是软金属，因此可以相对容易地通过摩擦搅拌焊接进行连接。现有的FSW研究集中在铜的制造上（无氧铜）核废料容纳罐，1-6通过FSW密封焊接制造溅射装置的铜背板，7，8和一些其他应用，9而迄今为止对铜合金的FSW研究很少有记录。10，11相关研究主题包括铝合金与铜合金异种接头的研究12，13以及--尽管与搅拌摩擦焊不完全相同--用于铸造结构改性的镍铝青铜的搅拌摩擦处理14 -16和用于表面改性的铜锰合金的搅拌摩擦处理17。
Abstract Copper, through having good thermal conductivity and a relatively high melting point, generally requires preheating treatment to maintain satisfactory penetration during arc welding, ranking as a hard-to-weld material. Like aluminium and magnesium, however, copper is basically a soft metal and can therefore be relatively easily joined by friction stir welding. Available FSW research has focused on fabrication of copper (oxygen-free copper) containment canisters for nuclear waste,1–6 fabrication of copper backing plates for sputtering devices by FSW seal welding,7, 8 and some other applications,9 whereas FSW research on copper alloys has thus far been little documented.10, 11 Related research topics include studies of Al alloy to Cu alloy dissimilar joints12, 13 as well as – although not quite the same as friction stir welding – friction stir processing of Ni–Al bronze for casting structure modification14–16 and friction stir processing of a Cu–Mn alloy for surface modification purposes.17
