摘　　要：介绍了鞍钢开发的建筑耐火结构钢Q345B-Fr的焊接性及焊接接头的组织性能。使用相匹配的E5015NiMo手工焊条,焊接接头具有良好的综合力学性能和抗高温强度,在600℃保温2h条件下,高温强度大于常温强度的2/3。This paper describes the welding properties of Q345B - Fr construction refractory structure steel and the structure properties of the welding joint. Comprehensive machinery properties and strength resistance to high temperature are good at welding joint while using adapted E.5015NiMo manual welding electrode. Strength of the welding joint at high temperature is 2/3 more than that at home temperature while keeping at 600℃ for 2 hours.
