Cabrera booked his place with a 2&1 win over Hunter Mahan, while Els trailed Henrik Stenson by one hole after the morning round but recovered to win 3&2.
Six-time winner Els had five birdies in his afternoon round to reach the final.
US Open champion Cabrera shot 66 in the morning round to lead by three holes and was up by six strokes at one point before his American opponent rallied.
Angel beat me last year - he is going to be a tough opponent."
The final, which has a £1m prize for the winner, sees an Argentine take on a South African on the same day that their respective nations meet in their semi-final at the rugby union World Cup in France.
Cabrera and Els have met twice before in the World Match Play, with one victory each.
"He got me last year," Els told BBC Sport. "He is going to be a tough opponent."
The 37-year-old Cabrera shot nine birdies and two eagles over the 35 holes played in his semi-final.
Cabrera, who defeated defending champion Paul Casey on Friday, said: "I am really delighted.
"I played some of my best golf. Hunter came back strong and it was a tight match and I am pleased to have won."
Cabrera led from the second hole and it looked as though he would record a comfortable win when he moved six ahead after four holes of the afternoon round.
But Mahan chipped away it Cabrera's advantage and with two holes to play had reduced the Argentine's lead to two strokes.
Mahan sunk a 10-footer but Cabrera held his nerve to putt from a similar distance and book his place in the final.
In the other tie, Stenson had birdied the 18th to take the lead in the morning after a round that had seen him move one up three times, only for Els to square the match on each occasion.
Els had beaten Colin Montgomerie and Andres Romero in the first two rounds but had a difficult time on the greens in the morning.
The world number five three-putted to fall behind on the short second and had chances to level on every green from the fifth to the 10th, but was unable to take any of them.
However, Els was in superb form in the second half of his semi-final contest.
And after taking the lead for the first time in the tie at the seventh hole, Els never looked back.

"When I got my nose in front I felt relieved and free again," said Els.
"I struck the ball nice on the front nine but then hit a bad tee shot at the 10th. After that I ground it out.
"The putter saved the day in the afternoon - I could not buy a putt during the morning round."
