Research on Welded Structure of H62 Blade and Q235A Hub |

| Abstract: | Since the physical properties and chemical properties of H62 blade of draw-out type ventilating machine are markedly different with that of Q235A hub,usually some welding performance disadvantages are inevitable such as blade falling off and blade fracture.A new structure and the corresponding welding process of blade and hub are presented in this paper,which can enhance blade tensile strength and improve the safety and reliability. |
