autogène

Autogène is a French term that translates to "autogenous" in English. It refers to something that originates from within or is self-generated. The term is most commonly encountered in the context of welding, specifically autogenous welding. In this type of welding, no additional filler material is used. The joint is created by melting the edges of the base metals themselves, allowing them to fuse together as they cool. This process relies on the inherent properties of the materials being joined.

Beyond welding, the concept of autogène can also be applied to other fields. For instance, in geology, autogenous processes describe formations or changes that occur within a system without external influence. Similarly, in biology, autogenous regeneration refers to a process where an organism or tissue can repair itself using its own resources. The core idea remains consistent: the origin and driving force come from the subject itself, rather than an external agent. This self-sufficiency is the defining characteristic of autogène.
