A welding process in which a weld is produced in a butt joint by
slowly bring the parts together and applying pressure while a high
density of current fuses the mating surfaces. - ANSWER-flash
welding
What welding process do the following characteristics describe?
-some force is applied before the welding current is switched on
-typically no melting occurs
-only parts with interfaces equal in cross-sectional area can be
joined
-higher quality joints are required for adequate resistance heating
- ANSWER-upset welding
what welding process is similar to flash and upset welding, but
produces an arc by a rapid electrical discharge over a decreasing
air gap, with pressure applied during or immediately after
electrical discharge - ANSWER-percussion welding
