Treatment of API standard 650 flat-bottom tanks welding defects:1. Lack of fusion: once found, it should be shoveled and grinded off before re welding.2. Incomplete penetration: over standard defects shall be removed and re welded. When welding on both sides, the shallow side of the groove can be grinded and shoveled to expose the welding root on one side, and then the welding is repaired.3. Slag inclusion: over standard defects shall be removed and re welded.4. Crater: weld to full after grinding.5. Air hole: if the internal air hole exceeds the standard, it shall be welded again after being removed by grinding shovel, and the surface air hole shall be removed by grinding wheel and then repaired.
