Step 1: Check the location and type of marine ring damage. Common ocean ring damage can be divided into surface scratch, aging blackening, ocean ring edge deformation and ocean ring cracking gap.

Step 2: Determine the appropriate repair process according to the damage of the ocean ring and start the initial grinding of the hub.

Step 3: If there is deformation and crack gap in the ocean ring, it is necessary to shape and weld the hub body first, put the ocean ring on the ocean ring shaper, shape the deformed area, and detect the repaired area with testing instruments to ensure the normal circumference of the ocean ring.

Step 4: After the final welding, the welded part of the ocean ring needs polishing, and check whether the whole ocean ring is uneven and whether there is any place where the primer is not cleaned.
