Mold steel is a special steel used to make molds, which has the characteristics of high hardness, high strength, high wear resistance and high heat resistance. In the process of mold making, it is often necessary to carry out welding repair or joining work. Choosing the right electrode has a significant impact on the quality of the weld and the life of the tool. The following will introduce several commonly used die steel welding rods and their characteristics.
H13 electrode.
H13 electrode is a commonly used die steel welding material, which is suitable for welding H13 die steel. It has good heat resistance and wear resistance, and can maintain good hardness and strength at high temperatures. H13 electrode also has good crack resistance and impact resistance, which can effectively prevent cracks and fractures in welded joints. In addition, the H13 type electrode also has good weldability and machinability, which is easy to operate and process.
2.P20 electrode.
P20 type electrode is a welding material suitable for welding P20 type die steel. P20 type electrode has good hardness and strength, and is able to maintain stable performance at high temperatures. It also has good wear resistance and corrosion resistance, which can effectively extend the service life of the mold. The P20 electrode also has good weldability and machinability, which is easy to operate and process.
3.Type 718 electrode.
Type 718 electrode is a welding material suitable for welding type 718 die steel. Type 718 electrode has good heat and wear resistance, and can maintain good hardness and strength at high temperatures. It also has good crack resistance and impact resistance, which can effectively prevent cracks and fractures in welded joints. Type 718 electrode also has good weldability and machinability, which is easy to operate and process.
4.Stainless steel electrodes.
In some special cases, the die steel needs to be treated with stainless steel to improve its corrosion resistance. At this point, stainless steel electrodes can be selected for welding. Stainless steel electrodes have good corrosion resistance and heat resistance, and can maintain good performance in high temperature and corrosive environments. Stainless steel electrodes also have good weldability and machinability, which is easy to operate and process.
In conclusion, choosing the right electrode has an important impact on the welding quality and mold life of the die steel. When choosing a welding rod, you need to consider factors such as the material of the die steel, the working environment, and the welding requirements. At the same time, it is also necessary to pay attention to the control of the welding process to ensure the quality and performance of the welded joint. Finally, when welding repair or connection, it is necessary to operate in strict accordance with welding specifications and operation requirements to ensure welding quality and mold life.
