Notes:

1. Before welding, the surface of the steel plate needs to be cleaned thoroughly to ensure welding quality. Because there may be impurities such as oil stains and dirt on the surface of the steel plate, which can affect the welding quality. So it is necessary to use detergent or other cleaning agents to clean the surface of the steel plate.

2. When welding 20MnHR steel plates, it is necessary to choose the appropriate welding method. Generally speaking, commonly used welding methods include manual arc welding, argon arc welding, and submerged arc welding. Different welding methods have different effects on welding materials, so it is necessary to choose the appropriate welding method according to the specific situation.

3. Choosing the appropriate welding electrode is also very important. When welding 20MnHR steel plates, it is necessary to choose electrodes with good heat resistance and pressure resistance. Only by selecting the correct electrode can welding quality be guaranteed.

4. When welding 20MnHR steel plates, it is necessary to ensure that the welding temperature does not exceed the hot deformation temperature of the steel. Because if the welding temperature is too high, it can cause deformation or cracking of the steel plate, thereby affecting the welding quality.
