摘要

为设计合理的感应线圈结构，并探究不同输入电流、加热时间对焊缝温度最大值的影响，选取适合的工艺参数，从而实现蜂窝板感应钎焊的高效率制备。本文建立了感应钎焊蜂窝板的有限元模型，设计了3种形状的线圈：螺旋形线圈、双回形线圈、M形线圈，并计算得到3种线圈感应钎焊蜂窝板的温度场分布，同时探究了不同工艺参数对温度最大值的影响规律。在模拟的基础上，对Ti

AlNb合金和高温合金组成的蜂窝夹层结构进行钎焊试验，验证了感应钎焊Ti

AlNb/GH4099蜂窝夹层结构具有良好的可行性。结果表明，螺旋形线圈在焊缝处的磁场更加集中，产生的电磁热更多，钎焊效率更高。螺旋形线圈更利于感应钎涂过程中产生大量电磁热，并且当电流为1 000 A，加热时间为15 s时钎焊效率最高，且实验得到的Ti

AlNb/GH4099蜂窝夹层结构力学性能优异。

Abstract

To design a reasonable induction coil structure and investigate the effects of different input currents and heating times on the maximum value of the weld temperature

and to select suitable process parameters

so as to realise the high-efficiency preparation of honeycomb plate induction brazing. In this paper

a finite element model of induction brazing honeycomb plate is established

three shapes of coils are designed: spiral coil

double-back coil

M-shaped coil

and the temperature field distributions of induction brazing honeycomb plate with the three kinds of coils are obtained by calculations

and the influences of different process parameters on the maximum value of the temperature are also investigated. On the basis of simulation

brazing test was carried out on honeycomb sandwich structure composed of Ti

AlNb alloy and high-temperature alloy

and it was verified that induction brazing Ti

AlNb/GH4099 honeycomb sandwich structure had good feasibility. The helical coil concentrates the magnetic field more at the weld seam

generates more electromagnetic heat

and has a higher brazing e

fficiency. The spiral coil is more conducive to the generation of a large amount of electromagnetic heat in the induction brazing process

and the brazing efficiency is highest when the current is 1000A and the heating time is 15s

and the mechanical properties of the experimentally obtained Ti2AlNb/GH4099 honeycomb sandwich structure are excellent.
