加氢反应器堆焊层铁素体含量对焊接工艺的影响

Influence of ferrite content in hydrogenation reactor surfacing layer on welding process

阐述了不锈钢堆焊层中铁素体的存在对焊缝的影响以及测定铁素体含量的方法,研究了化学分析和磁性2种测量方法测得的铁素体含量的差异及焊接参数对铁素体含量的影响。

This paper expounded influence of the existence of ferrite in stainless steel surfacing layer on welding seam andthe determination method for ferrite content,and researched the difference of ferrite contents determined with chemicalanalysis and magnetism and the influence of welding parameters on ferrite content.
