The switching properties of brazed and welded contact assemblies is strongly
dependent on the quality of the joint between the contact and the carrier. The
of relevant process parameters and by sampling of finished products.
===3.4.1 Brazed Joints===
Despite optimized brazing parameters non-wetted defect areas in the braze
joint cannot be avoided completely. These wetting defects can mostly be traced
non-destructive methods.
===3.4.1.1 Destructive Testing===
Destructive tests can be performed on a sampling basis in rather simple ways:
brittle contact tip materials such as for example tungsten.
===3.4.1.2 Non-Destructive Test Methods===
Typically the non-destructive testing of braze joints requires more elaborate test
equipment. Besides this such test methods have limitations regarding the
assemblies.
===3.4.2 Welded Joints===
Since welded contact assemblies are usually produced in rather high quantities
the quality of the weld joints is monitored closely. This is especially true because
assemblies ''(Fig. 3.16)''.
===3.4.3 Selection of Attachment Methods===
In the preceding sections a multitude of possibilities for the attachment of
contact materials to their carriers was described. A correlation of these
