Latest Patents
Yeon-Chae Jeong holds a patent for a welded member of galvanized steel sheets. This invention includes a first steel sheet that consists of a base steel sheet and a zinc-based plating layer formed on its surface. The second steel sheet is spot-welded onto the first steel sheet, facing the zinc-based plating layer. The design features a spot-welded zone formed between the two sheets. Notably, the surface layer of the base steel sheet has a decarburization ratio of 30% or more, which is crucial for its performance. The decarburization ratio is calculated using a specific equation that considers the average carbon concentration in the surface layer compared to the bulk carbon concentration. Additionally, the shoulder portion of the spot-welded zone includes a B-type crack of 100 μm or less, while no C-type crack is present.
