不锈钢与碳钢插入式管板焊接工艺方案研究

在压力容器等特种设备的制造过程中,对于焊接工艺评定0Cr18Ni9不锈钢板与20#碳钢管子插入式管板焊条电弧焊型式试验件的制作,给我们的生产效率带来很大阻力。按照评定标准要求将两套试验件十字分割后做金相分析。通过分析发现缺陷率已达到25%,与标准要求相差甚远。为了降低焊接缺陷率,我们进行了数据统计、原因分析、确定要因,制定对策和措施,最终研究出一套可行焊接工艺方案,保证了此类焊接接头的焊缝质量。     

宝钢冷轧热镀锌机组辐射管更换技术总结

辐射管被广泛地应用在宝钢厂冷轧区域热镀锌、连退机纽加热炉段，辐射管自重较大，其法兰面是通过焊接的形式与加热炉炉壁连接，从而保证耐高温、密封和受力的相关要求。目前，辐射管的更换采用配重吊具抽出辐射管、手工普通电弧焊进行辐射管焊接的方法，更换效率低，因此通过对吊具改进以及采用先进的焊接方法来提高辐射管更换效率显得尤为重要。     

单面焊双面成形质量差的原因及防止措施

单面焊双面成形技术是采用普通焊条，在不需要任何辅助措施条件下，只是坡口根部在进行组装定位焊时，应按焊接的不同操作手法留出不同的间隙，在坡口的正面进行焊接，就会在破口的正、背两面都能得到均匀整齐、成形良好。符合质量要求的焊缝。这种方法主要适用于板材对接接头、管状对接接头和骑座式管板接头。是锅炉、压力容器焊工应熟练掌握的操作技能。
