Experimental study on electro-slag weld of blast furnace steel using vibratory conditioning technology

Vibratory conditioning technology was used in the electro-slag welding of blast furnace steel and mechanical properties of welded joint were measured.The results have proved that vibratory conditioning technology can effectively improve the comprehensive properties of welded joints.Especially,at the 0.6 acceleration of gravity vibratory state,the qualification rates of side bend performance are up to 100%.
