Title: Yongchao Su: A Pioneer in Resistance Spot Welding Innovations
Introduction
Yongchao Su, an accomplished inventor based in Shanghai, China, has made significant contributions to the field of resistance spot welding. With a total of two patents to his name, Su focuses on innovative methods that enhance the performance and reliability of welding processes, particularly for high-strength steel.
Latest Patents
Yongchao Su's latest patents include a groundbreaking method for resistance spot welding of galvanized high-strength steel, which exhibits exceptional joint performance. This method utilizes three welding pulses within a single spot welding schedule. The first welding pulse initiates the generation of a nugget, while the second pulse is strategically applied to suppress the formation of liquid metal embrittlement (LME) cracks. This dual approach yields a nugget diameter between 3.75T and 4.25T, where T denotes the plate thickness. The third pulse, a tempering pulse, is crucial for enhancing the plasticity of the welding spot.
Another notable patent involves the development of a steel welding component featuring an aluminum or aluminum alloy coating. This innovative welding blank consists of a steel substrate bonded with an intermetallic compound alloy layer, along with a metal alloy layer atop it. Importantly, the coating is meticulously removed from the area to be welded, facilitating optimal weld integrity and performance. Su's contributions ensure improvements in tensile strength, elongation, and corrosion resistance in hot-stamped welded joints.
