锅炉集箱和管道对接焊坡口的改进研究

A study of the improvement of the butt weld groove of a boiler set box and pipe

合理的坡口设计有利于保证焊缝质量。本文针对锅炉集箱和管道 (δ =6 mm～ 14m m)对接焊时常采用的V型坡口易出现问题 ,提出了一种改进型坡口。分析及试验结果表明 :改进型坡口优于 V型坡口 。

The rational design of a groove helps insure the quality of a welded seam In this paper, an improved groove was offered in accordance with the problem which arises easily on the V type groove while the boiler set box and the pipec (δ=6mm^14mm) are welded together The analysis and experiments have shown that the improved groove is better than the V type one, and will help insure and improve the quality of welding
