What is the main disadvantage of the spot welding process? -
ANSWER-material thickness is limited
What makes resistance projection welding different from
resistance spot welding? - ANSWER-protrusions or embossments

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
