Do the preheating and postheating items conflict with the heat treatment of the weld joint?

First of all, preheating does not conflict with the heat treatment of the welded joint. Post heat and heat treatment of the welded joint are determined according to the specific situation. For example, if the overall heat treatment is performed after the equipment is manufactured, the welded joint still needs to be post heated. , Heat treatment should be carried out immediately after the welding is completed.
