कसरी स्टील कास्टिंग निर्माताहरूले स्टील कास्टिंग त्रुटिहरू मर्मत गर्छन्?

Steel casting manufacturers leave the factory with zero defects. Many steel casting factories will identify defects in time and rectify them during the processing of steel castings. Therefore, when we encounter a casting defect, how do we address it? What should I be mindful of?

1. When repairing the required steel castings through welding, a strict review of both the specific defect situation and the welding repair process operations is necessary.

2. When using gas cutting or carbon arc gouging to remove defects in steel castings, it's essential to preheat considering the chemical composition, defect size, and properties of the steel casting.

3. Product defects may be identified during quality and visual inspections, or during heat treatment or machining in a steel casting foundry. Upon detection of defects, they can be addressed through machining, chiselling, and gas cutting.

4. After a steel casting defect is repaired by welding, the repaired weld and the areas close to the base metal must be polished, and it must then be confirmed that the defect has been treated in accordance with the specifications regarding the number, size, and design drawings of the previous defect.

5. Once the defects found in the produced steel castings have been addressed, non-destructive testing is employed to verify and confirm that the defects have been completely rectified. If the shallow grooves or pits resulting from the defect do not compromise its strength, they can be smoothed into an arc-shaped transition surface, followed by the final inspection of the casting by the steel casting foundry, and the factory will proceed to ship the item after passing inspection.
