摘要
电站锅炉制造中,经常碰到的一个难题,即带有长管接头及焊有赛排鳍片的集箱制造。由于采用工艺技术不同,对制造质量带来影响。此文着重介绍采用先小拼排再与集箱组装的全新、合理的先进工艺技术,解决了焊后收缩变形、焊缝表面质量、几何尺寸公差难控制等问题。
A difficult problem frequently encountered in manufacturing of utilityboiler is manufacturing of headers with long nozzles and closely-spaccd fins welded. Thedifferent manufacturing technology applied will bring influence to manufacturing quality.This paper emphatically introduces a new, reasonable and advanced manufacturingtechnology by first small panel splicing and then assembling with the header, so to settleproblems such as post-weid contracting deformation, weld surfaee quality, difficulty incontrol of geometric dimension tolerances.
