Fuse and unite both make things one, with a difference in completeness and feeling. Fuse is to join two things into one, usually by melting, so completely that the seam disappears. Unite is to join parts or people into one for a shared cause, with a sense of solidarity. Fuse welds things into one inseparable whole; unite joins them, standing as one, for a purpose.
Both end in one, but fuse melts the parts together while unite keeps them, joined. Fuse, from Latin fundere 'to pour or melt', joins two things so completely that you cannot find the join. Unite, from Latin unus 'one', joins parts or people around a shared cause, each still there but standing together. Two metals fuse into one plate; a cause unites people who remain themselves. One is a seamless weld; the other a purposeful joining.
fuse
To fuse is to join two things into one by melting them together, so completely that the boundary is gone — metals fuse under heat, and by extension genres, ideas, and cultures fuse into something new. From the Latin fundere 'to pour or melt'. The same spelling names a very different noun: a fuse is the thin wire in a circuit that melts and breaks when the current runs too high. Where two edges coalesce under heat they fuse; unlike things that merely diverge, what is fused cannot be pulled apart.
unite
To unite is for separate people, groups, or parts to come together and act as one — from the Latin unus, 'one'. A crisis unites a divided nation; scattered rebels unite behind a leader; two kingdoms unite under one crown. The word carries a charge of solidarity: those who unite often stay distinct yet stand together, as allied armies do when they unite against a common enemy. To unify is to make one cohesive whole; to unite is to join forces — to combine strength while keeping your own name.

Ask whether the parts vanish or stand together. Fuse melts them into one with no seam — two plates run together into a single piece. Unite keeps them, joined for a purpose — scattered figures still themselves, but hand in hand as one ring. If two things melt into one inseparable whole, that is fuse; if people or parts join for a cause, that is unite.

Fuse makes two things one inseparable whole, usually by melting, and the parts lose their edges; unite joins people or parts for a purpose, and they keep their identity while standing as one. Fuse suits physical and creative joining; unite suits people and causes. Fused things cannot be pulled apart; a union can, in principle, be dissolved.
