氟化物A-TIG焊接Ti6Al4V的电弧行为

  • 摘要: 试验选用MF型氟盐(LiF,NaF,KF)、MF2型氟盐(MgF2,CaF2,BaF2)和KN型钾盐(KF,KCl,KBr)对氟化物A-TIG焊接Ti6Al4V的电弧行为进行了研究. 结果表明,LiF和KBr活性剂不会影响A-TIG焊电弧行为;KF和CaF2活性剂会显著收缩电弧,增加电弧温度,但不会影响电弧力;MgF2活性剂能显著收缩电弧,增加电弧温度,并能增大电弧力;BaF2活性剂不会影响电弧形态,但能增加电弧温度,减小电弧力;NaF和KCl活性剂可以不同程度地收缩电弧,增加电弧温度,但不会影响电弧力. 此外,A-TIG焊接Ti6Al4V应优先选用氟化物作为活性剂,在MF型氟盐中应优先选用KF,在MF2型氟盐中应优先选用MgF2.
