[日本]以日本秋田县立大学系统科学技术学部的日置进教授为首,开发了加热摩擦搅拌接合方法,由于该方法采取加热金属构件,与传统方法相比,接合速度提高了2~3倍。开发的方法,利用了材料随着温度升高容易产生塑性流动的材料性质,接合时,适当地加热被接合材料,通过搅拌以促进材料的 [Japan] Japan’s Akita University Department of Systems Science and Technology led by Professor Nikko Hitachi, developed a friction stir welding method, the method of heating metal parts, compared with the traditional method, the bonding speed increased by 2 to 3 times. The developed method utilizes the material properties of a material that easily undergo plastic flow with increasing temperature and, at the time of joining, the material to be joined is appropriately heated and the material of the material is accelerated by stirring
