Not only magnets, but metal repel. There are two kinds of charges that metal contain, positive and negative. If you push a positively-charged magnet towards another positively-charged magnet, they'll repel, maybe because one type of charge needs the other to attract. If this one type of charge comes close to another charge of the same kind, it won't receive what it needs, and feel "resent" to the other charge, then repel. If you push a negatively-charged magnet towards another negatively-charged magnet, they will also repel.
Two like charges (either two positive charges, or two negative charges) will repel one another.

Weld is a verb which means joining two pieces of metal together.
When two pieces of metal touch in space, they become PERMANENTLY stuck together. This happens because of the lack of gravity in space
when you weld metal, you are combining the two masses by overcoming the electromagnetic repulsion of the electrons to each other when you bang metal together, there is not enough energy to overcome the repulsion, so the two pieces stay separate
they repel. opposites attract!

Spelled RIVET. It sets a metal fastener (a rivet) that permanently joins two pieces of metal.
