Joining parts by melting them together is known as

brazing
fusion welding
soldering
spot welding

The correct answer is: brazing

Brazing involves joining parts by melting and flowing a filler metal into the joint, whereas fusion welding involves melting the base metal itself to join parts. Soldering, on the other hand, involves joining parts by melting a lower melting point filler metal that bonds the parts together without melting the base metals. Spot welding is a process that joins metal parts by applying pressure and heat through electrical resistance to create a weld at designated spots. Therefore, the correct answer here is brazing because it specifically refers to joining parts by melting them together using a filler metal.
