本文简要介绍了钛管与钛钢复合管板胀接工艺及采用手工钨极氩弧焊的焊接工艺。并经液氨致冷器的制造实践证明,钛管与钛钢复合管板在选择合理的制造工艺的前提下,可以获得优质的焊缝,同时为钛及钛钢复合板换热设备的制造积累了一定的经验。
This article briefly introduces the titanium tube and titanium steel composite tube expansion process and the use of manual TIG welding process. The manufacturing practice of the liquid ammonia cooler shows that the titanium tube and the titanium steel composite tube plate can obtain the good weld under the premise of choosing a reasonable manufacturing process and meanwhile manufacture the heat exchange equipment for the titanium and titanium steel composite plate Have accumulated some experience.
