| Abstract: | 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. |
