| Abstract: | Mainly studied overlay welding to repair for hot die based on 5CrMnMo.Selects D397 and the D337 welding rods as the material of overlay welding,and taking the direct-current and the opposite method to repair by manual welding for 5CrMnMo hot die steel.Have also used the metallographic microscope and the microhardness to observe,tested and analyzed structural appearance and hardness of the overlay welding layer under the different conditions of welding.Fine quality welding tie-in can be produced with selecting D397 welding rods. |
