铁基高铬镍耐热合金焊接工艺

Welding Process of Heat-resistance Ferroalloy with High Cr-Ni Content

以制氢装置改造工程为例 ,报道在制氢转化炉炉管现场焊接施工中 ,对铁基高铬镍耐热合金管材的成功焊接 ,包括可焊性分析、焊接工艺评定试验、焊接工艺措施和质量检验。

By taking the modification project of hydrogen generation unit in a petrochemical plant as an example, the successful welding of heat-resistance ferroalloy with high Cr-Ni content is presented, including weldability analysis, weld procedure qualification test, weld process measures and quality inspection.\;
