zone of heating

Firstly, the paper established the finite element model of different thickness TWB and divided the geometric model into non-uniform finite element mesh combining the structural characteristics of TWB. the plasma arc heating zone and heat-affected zone were also considered.

首先结合拼焊板的结构特点以及等离子体弧加热区与热影响区尺寸，建立差厚拼焊板的有限元模型并划分不均匀的有限元网格。

Fitting to lower melting point of tin-lead solder, the length of zone of heating is 150mm;

由于含铅钎料熔点低，受热区长度只要150mm就可以了。

The experiments results of different heating rate show that TG curves move to high temperature zone with the increasing of heating rate.

不同升温速率的实验结果曲线表明，提高升温速率，TG曲线向高温方向移动；

The influence of weld heating on microstructure of heat affected zone was investigated in this paper.

探讨了焊接加热对热影响区组织的影响.

Is located in Guangzhou Zone, Guangzhou City, the focus of electricity production and district heating companies.
