Notes:
1. Impurities such as rust, oil, and moisture must be removed from the weldment before welding.
2. The energy of the welding line will directly affect the mechanical properties of the weld. The magnitude of the line energy depends on the level of importance of the structure. The more important the structure, the smaller the line energy should be used.
3. The welding parameters provided are for reference only. The user should formulate the welding specification for suitable production according to the specific situation.
