But Kieran Molloy had to settled for a top eight finish after losing his quarter-final bout this afternoon.
Hession forced Bashir Bajwa of Germany into a standing count in round three en route to a commanding win.
The Irish champion, showcasing head and body shots, took rounds one,two and three comprehensively.
Clancy and France’s Lounes Hanraoui were involved in an extremely close bout with the French light welter taking the first round 4-1, but Clancy, constantly edging toward his opponent, taking the second 3-2.
That left it all to play for in the third and final round, and Clancy, who landed a well-timed combo late in the frame, took the decision and a guaranteed bronze.
Molloy had to contend with a harsh public warning for dropping his head and a cut near his left eye in the second round against Akbar. The Galway welter found the target with some solid punches throughout this encounter but his opponent, the No. 1 seed, was not to be denied.
Meanwhile, Jack Marley posted a dominant win over Moldova’s Andrei Zaplitni to guarantee Ireland at least a third bronze medal.
Marley controlled the tempo and terms of this bout to earn four 30-27 scores and one 30-26 score in an emphatic win.
