Consolidate and join both bring things together, with a difference in scale and aim. Consolidate is to combine scattered things into one stronger, firmer whole, or to make a position more secure. Join is the plain, broad word for connecting two things directly, or becoming a member of a group. Consolidate strengthens several into one solid whole; join simply connects or adds a member.
Both bring things together, but consolidate goes further and sounds far more formal. Consolidate, from solidare 'to make solid', draws loose things into one firm mass or secures a hold — several firms, debts or offices into one. Join, from Latin jungere 'to yoke', connects two things directly — two pipes, two hands — or adds a person to a group. A group consolidates its firms into one strong company; you join two lengths of chain. One makes several into a single strong whole; the other simply links, or adds a member.
consolidate
To consolidate is to make many into one solid — the Latin solidus sits unhidden in the middle of the word. Companies consolidate scattered offices; armies consolidate gains before advancing; the sleeping brain consolidates the day's learning into memory. The trade is always the same: a dozen small, loose holdings exchanged for a single firm one. What is consolidated stops being a collection and becomes a structure — and structures, unlike collections, do not blow away.
join
To join is to connect two things directly, or to become part of a group — join two pipes end to end, join a club, join hands. From the Latin iungere, 'to yoke'. At its simplest it makes one continuous thing out of two: where two roads meet, they can be joined into a single route. With people it means to enter or take up with — you join a team, join the queue, join forces. Unlike things that merge into one body, joined parts keep their own ends; they are linked, not dissolved.

Ask how many, how strong, how formal. Consolidate draws several scattered things into one firm, secure whole — tiles locked into a slab that no longer skids. Join simply connects two things, or adds a member — a fresh link closing two chains into one run. If scattered things are made one stronger whole, that is consolidate; if things are directly connected or someone signs up, that is join.

Join is one of the plainest words in English and covers almost any connecting or membership; consolidate is formal, about several scattered things made into one stronger whole. You join a club, join two wires, join hands — none of which is 'consolidate'. They overlap only when several things are combined, and even then consolidate stresses the strength of the result.
A clear register pair. Join is the everyday, all-purpose verb — join two parts, join a group, forces join. Consolidate is the formal choice when the point is strengthening several scattered things into one firmer whole — 'consolidate the firms', 'consolidate power', 'debt consolidation'. Examiners reward the fit: join for simple connecting or membership, consolidation for a stronger combined whole. Note join gives the noun a join or a joint, whereas consolidate gives consolidation.
