- 論文の詳細を見る
Weldability, or the formation of the sound nugget is influenced by various factors, such as electric current, electrode force, welding speed, shape of electrode tip and initial gap between work pieces. This makes it difficult to select the appropriate welding conditions and to control them dynamically during welding. To solve such problems, finite element methods are developed for numerical simulations of resistance spot welding and seam welding. The usefulness of the proposed methods is demonstrated through examples.
