【摘要】：超聲復合焊接是功率超聲應(yīng)用的重要方向之一。由于超聲獨特的物理化學與力學效應(yīng),改變或改善了傳統(tǒng)焊接工藝的效果,甚至解決了傳統(tǒng)焊接無法克服的問題,因此,該技術(shù)在制造工業(yè)中具有潛在的應(yīng)用前景。但是,目前的研究偏重超聲復合焊接工藝效果,在超聲能與焊接能復合機制方面的研究不夠深入,對該方法能夠達到的水平不清楚。綜述超聲復合焊接中三種主要方法——超聲復合電弧焊、超聲復合釬焊和超聲復合攪拌摩擦焊的工藝原理、特點及成果,歸納與總結(jié)焊接工藝中超聲場作用下液態(tài)金屬凝固行為、固態(tài)金屬流變成形行為、液態(tài)釬料合金與母材的界面行為,提出目前研究中所存在的主要科學問題及建議未來應(yīng)關(guān)注的幾方面內(nèi)容,希望對該領(lǐng)域的基礎(chǔ)研究及工程應(yīng)用提供有價值的參考。
[Abstract]:Ultrasonic composite welding is one of the important directions of power ultrasonic application. Because of the unique physical, chemical and mechanical effects of ultrasonic, the effect of traditional welding process has been changed or improved, and even the problems that can not be overcome by traditional welding have been solved. Therefore, this technology has a potential application prospect in manufacturing industry. However, the current research focuses on the effect of ultrasonic composite welding, and the research on ultrasonic energy and welding energy recombination mechanism is not deep enough, and the level that this method can achieve is not clear. This paper summarizes the principle, characteristics and achievements of three main methods in ultrasonic hybrid welding, namely, ultrasonic composite arc welding, ultrasonic composite brazing and ultrasonic hybrid friction stir welding. The solidification behavior of liquid metal, the rheological forming behavior of solid metal, the interface behavior between liquid solder alloy and base metal under ultrasonic field in welding process were summarized and summarized. This paper puts forward the main scientific problems existing in the present research and some suggestions for the future, and hopes to provide a valuable reference for the basic research and engineering application in this field.
