→Welding Processes
Welding of contact assemblies has both technological and economic importance. Because of the short heating times during welding the carrier materials retain their hardness except for a very small heat affected area. Of the methods described below, resistance welding is the most widely utilized process.
Because of miniaturization of electromechanical components laser welding has gained some application more recently. Friction welding is mainly used for bonding see [[Applications for Bonding Technologies|Applications for Bonding Technologies .]]. Other welding methods such as ball (spheres) welding and ultrasonic welding are today used in only limited volume and therefore not covered in detail here.
Special methods such as electron beam welding and cast-on attachment of contact materials to carrier components are mainly used for contact assemblies for medium and high voltage switchgear.
