The tool joints made by forging are heat treated by quenching and tempering. They are either friction welded or flash welded to the pipe body. For friction... [Pg.1257]

Avoid the use of shrink-type tool joints on drillpipes and drill collars (connectors, in this case). Flash-welded tool joints for drillpipes and integral drill-collar joints should be used. [Pg.1340]

The following abbreviations are used DSA, double submerged-arc welded EFW, electric fusion welded ERW, electric resistance welded FW, flash welded, and S, seamless. [Pg.215]

The nanoscale structure of polyaniline nanofibers produces enhanced polymer functionalities their polymeric nature also yields new nanoscale physicochemical phenomena that have not been observed in inorganic nanostructured materials. In this section, a flash welding technique is presented based on an enhanced photothermal effect discovered with the polyaniline nanofibers. [Pg.240]

Flash-welded films can be readily removed from their substrates by water. They can also be peeled off by touching a corner to cellophane tape, leading to a free-standing nanofiber film (Figure 7.43, upper left). [Pg.241]

FIGURE 7.43 SEM images showing the cross section of an asymmetric free-standing nanofiber film produced by flash welding. The inset picture shows that the welded films become insoluble in N,N-dimethylformamide (DMF). The pale blue color is due to partial dissolution of uncross-linked polyaniline.

Be sure that suitable spark shields are used around equipment in flash welding. [Pg.388]

Flash and pressure welding both involve the application of heat and pres-svue. The major difference is the degree of heating. Flash welding requires actual melting of the metal at the joint, while the metal during pressiire welding is heated to a plastic state. [Pg.766]
