Gordon Edwards, 29, and Liz Antrobus, 22, both badly injured when they were blown across the street by the second of two blasts, were married at Helsby, Cheshire.
Johnathan Ball, aged three, and Tim Parry, 12, were killed in the explosions on 20 March last year. Tim's mother, Wendy, was at yesterday's ceremony.
The bride, who wore a cream-and-pink dress and arrived in a Rolls-Royce, said: 'I still find it hard to walk any distance without a crutch, but I promised myself I would leave it at home on my wedding day.'
Doctors worked for a total of more than 12 hours to save the couple's limbs. The pair spent three months in hospital.
Mr Edwards, a canal
tug engineer from Runcorn, Cheshire, suffered severe leg injuries - including six fractures to his left leg - and internal bleeding caused by being hit in the stomach by shrapnel from the blast. The bride, a waitress from Helsby, suffered severe injuries to her right leg and left arm.
The couple had been engaged for just over a year when the blasts happened.
'We'll never forget what happened but we want to get on with our lives,' she said.
