When welding this steel, preheat the workpiece to 3~3℃, and the temperature of the welding zone shall not exceed ℃. Tempering treatment should be carried out in time after welding. The cooling rate at the beginning of tempering is ~℃/the steel is welded During the process, the temperature difference between the welding point and the surroundings should be ℃. During surfacing, the current in the first and second layers should be small and the weld beads should be thin, so that the heat affected zone will be shallow, the heat transfer will be less, and the welding zone or toughness will be good. It is recommended to use soft welding wire when welding, such as American Series 3 welding wire, which can improve the ability to resist crack expansion.
