The application and economic benefits of welding repair technology in manufacturing and maintenance

During manufacturing processes such as casting, forging or welding, parts may develop defects such as pores, shrinkage cavities and cracks. Welding repair technology restores the integrity of parts by introducing filler materials to fill these defects. Take the shrinkage cavities that occur in large cast steel parts as an example. Welding repair technology can effectively prevent the further expansion of defects and avoid the scrapping of parts due to defects.

For parts that have worn out due to long-term use, such as cutting tools in mechanical processing and wear-resistant components in mining equipment, welding repair technology can be applied to restore the worn areas. By adding wear-resistant materials to the worn parts for welding repair, the size and performance of the parts can be restored, thereby extending their service life.

In certain specific situations, welding repair technology can be used to enhance the functionality of parts. For instance, in steel structure buildings, the load-bearing capacity of the structure can be enhanced by adding reinforcing plates to the existing beams or columns through welding.

When the product design changes, welding repair technology can be applied to modify the existing parts. For instance, during the modification of automotive parts, new structures or components can be added to the original parts through welding and repair techniques to meet new design requirements.

For some large, complex or expensive parts, if they are scrapped directly after local defects occur, it will lead to a huge waste of costs. Welding repair technology can to a certain extent fix these defects, enabling parts to continue to be used and thus saving material costs and production costs. For instance, if a large Marine propeller suffers local damage, the welding repair technology can avoid remanufacturing the entire propeller, significantly reducing the maintenance cost.
