Evolution of Joining Technologies in Closures - (ppt): Technology overview with unique application examples

摘要

Indirect welding with a dimple: The dimple ensures the contact through the sealer; The dimple has a minimum contact surface with a high resistance; The dimple ensures a quick weld with high energy input at the right place; The dimple defines the exact quantity of material to be melted; The highest current density is between parts material which Is an advantage for electrode wear.
