The duo is among the top European athletes and is one of Sweden's medal hopes at the European Athletics Championships in Birmingham, which began on Monday.
Neither had any trouble meeting the qualifying mark of 18.20. Axelina Johansson threw 18.29 and Fanny Roos, with 18.72, advanced to the final comfortably.
It felt solid. It's great to be able to do it in the first round and be able to recharge for tonight, Fanny Roos told SVT.
The third Swede in the qualifiers, Victoria Wickman, missed the qualifying mark.
The shot put final begins tonight just after 8:00 p.m.
