Abstract :

Resistance spot welding is an important technique often used in joining thin work pieces in automobile, aerospace and packing industries, etc. This presentation theoretically and quantitatively investigates and interprets processes by realistically accounting for transient magneto-fluid mechanics, heat and species transport and bulk resistance in work piece and film and constriction resistances at contact interfaces. Since temperature gradient and solidification rate are found, the computed morphological parameter which is the ratio between temperature gradient and solidification rate shows that the effects of electrode geometries and material properties on growth of microstructures of the weld nugget can be interpreted, predicted and controlled.
