Steel is pretty forgiving and if there are no visible of feel-able faults you are probably ok.
Is the paint cracking on/near the weld? Do not heat them to bend them, it will soften the metal. Get them to a good frame repair shop, who should be able to re-cold set them, and advise you if there is any lasting damage.
Otherwise just get some of these: http://www.on-one.co.uk/i/q/FOOOP12/on_one_pompetamine_2012_fork
They are only £50, and the last thing you want is to be riding on damaged forks.
