摘要
以8mm和10mm厚的5456和2014铝合金板材为研究对象,讨论了2种材料对VPPAW焊接参数的敏感性,并就喷嘴孔径、喷嘴到工件距离和穿孔时间对焊缝成形的影响进行了分析,得到了中厚板铝合金VPPAW的焊接工艺,为后续研究奠定了基础。
By analysis of the subject investigated 8 mm or 10 mm thickness 5456 and 2014 aluminium alloy plates,compared the different sensibility of the two kinds of materials in VPPAW.Investigated how three parameters,the diametrical of aperture in nozzle,the distance between nozzle and work and the time for establishing the keyhole,influence the formation of weld in variable polarity plasma arc welding of aluminium alloys.The welding technology which is obtained by studying will lay the groundwork for future research.
