| Abstract: | According to special-purpose steel plate BB503 of oversize blast furnace hull, welding technology was studied with SMAW, KES and SES. Welded joints with three welding methods were analyzed on mechanical properties and microstructure by welding experiment. Main factors that influence the properties of welded joints were analyzed. It can improve the microstructure and properties of weld-joint with vibrating in welding process. The problem of vertical position welding of steel plate with 90 mm thick was resolved by vibrating KES welding. Welding technology of BB503 steel plate was confirmed on site. It came true that welding consumables were produced in China and welding quality was ensured. |
