不锈钢弯管部件钎焊的研究

Study of the Soldering of the Bends of Some Product

提出不锈钢钎焊时被预热和被钎焊的母材都不允许焊接区呈红色和亮黄色的新观点。论证了加热时氧——乙炔焰用微碳化焰的原因及焊缝结合区不能采用抛光的道理。指出了保证钎焊温度的方法及其原理等。

A idea is put forward that the soldered areas of both the parent material preheated and that soldered are not allowed to be red or bright yellow when stainless steel parts are.The reasons are given why weak carbonizing flame of oxyacetylece is used for heating and why brazing seam area can't be polished.The method to ensure proper soldering temperature and the principle for that is also dealt with.
