中心筒焊接工艺

Research on rotor cylinder welding technology

中心筒是电站锅炉空气预热器中的一个关键件和重要的受力件,而组成中心筒的筒身与端板角焊缝的焊接质量不易保证。通过研究焊接工艺试验,确定了焊接方法和焊接参数,解决了中心筒角焊缝的焊接质量问题,使中心筒角焊缝的焊接质量达到了Ⅰ级焊缝要求,为中心筒的批量生产奠定了基础。

Rotor post is a critical and important parts of air preheater. But the fillet welding quality is not easy to aehieve connected the tube and the end of air preheater, thruugh the welding technology research,After several test finally determined the wehting method and welding parameters,and solving the fillet welding problem of rotor post. The fillet weld quality of rutor post achieving the 1 class weld , at the same time ,It＇s a foundation for the batch production of rotor post.
