介绍了金属管高频焊接工艺及金属铝管高频感应焊接时焊接V形区各参数对焊接质量的影响。比较了采用真空管焊机和固态高频焊机进行感应焊时焊接区域各组件之间的相互关系,指出了两种焊机各自所使用的调整方法,以便提高焊接效率、获得良好的焊缝质量,同时给出了适用的V形角范围及焊接挤压辊的选用原则。最后,对铝管的高频感应焊接提出了10条建议。
The influence of welding V-zone parameters on welding quality is introduced when high-frequency welding process of metal pipe and high-frequency induction welding of metal aluminum pipe are introduced. The relationship between the components in the welding area when using vacuum tube welding machine and solid state high frequency welding machine is compared and the adjustment methods used by the two kinds of welding machines are pointed out to improve the welding efficiency and obtain the good weld quality , At the same time gives the applicable range of V-angle and the selection principle of the welding squeeze roll. Finally, the high-frequency induction welding of aluminum tube made 10 recommendations.
