The welding buildup repair for high-temperature corrosion prevention of the erosion surface of forged steel piston heads for diesel engines involves welding buildup on the worn piston crown and then performing special metal buildup welding on top of it, demonstrating extremely high corrosion resistance, thereby extending its lifespan and allowing for long-term use. Currently, piston crowns are manufactured through a complex forging process, which requires significant labor and is costly. Therefore, we have obtained a utility model registration certificate to manufacture piston crowns inexpensively and within a short period by cutting commercially available round rolled steel or round forged steel into specified lengths, machining them without undergoing a forging process, and then performing special heat treatment.

The welding build-up of forged steel piston heads for diesel engines is necessary because the piston crowns used in marine engines wear out due to explosive forces. When the wear exceeds a certain level, they must be discarded; however, with our new technique, they can be welded and reused. Not only can they be reused, but their wear resistance is also improved, making them stronger and longer-lasting than the original piston crowns. Currently, there are no approved welding build-ups of high-carbon forged steel by the Japan Marine Standards Association. This will be the first approval in Japan and the world.
