Briefly describe the technical requirements for parts processing and repair welding

   Technical requirements for parts processing and repair welding:

   1. Defects must be completely removed before repair welding, and the groove surface should be repaired smoothly and without sharp corners.

  2. According to the defects of the steel castings, the repair welding area defects can be removed by shoveling, grinding, carbon arc gouging, gas cutting or mechanical processing.

  3. The dirt, sand, oil, water, rust and other dirt within 20mm around the repair welding area and the groove must be thoroughly cleaned up.

  4. During the whole repair welding process, the temperature of the preheating zone of the steel castings shall not be lower than 350°C.

   5. When conditions permit, apply welding in a horizontal position as much as possible.

  6. During repair welding, the welding rod should not make excessive lateral swing.

  7. When the surface of steel castings is surfacing, the overlap between the weld beads shall not be less than 1/3 of the weld bead width.
