Joining technologies

As early as 1966, natural gas was available to all of the lower 48 states in the United States. During the period 1967—1990, the U.S. transmission system grew from 362,700 km to 450,800 km. Over this same time period, the distribution mains increased from 867,800 km to 1,347,000 km. As plastic pipe and reUable joining technology became available, the use of plastic pipe expanded to include the distribution of gas in low pressure systems. By 1990, approximately 24% of the U.S. distribution system was based on plastic pipe (1).

Alumina ceramics are used wherever exceptionally good dielectric properties, high mechanical strength and high thermal conductivity, coupled with a reliable ceramic-metal joining technology such as the moly-manganese process, are demanded. Examples of components are illustrated in Fig. 5.25.

Seam Position. As with other joining technologies, tracking of the seam may he desirable. This can be accomplished with standard off-the-shelf technologies. It can be simpler to implement for FSW because of the more henign operating environment (no arc, dust, or spatter) found with FSW compared to other processes.
