Notes on usage:
1 . Clear rust, oil, water and other impurities on the weldments before welding.
2. The size of the welding line energy will directly affect the mechanical properties of the weld. The size of the line energy depends on the important level of the structure. The more important the structure is, the smaller the line energy should be taken.
3. Welding parameters are only provided for reference. The user should develop an appropriate production welding specifications according to the circumstances.
