I wouldn't be using that myself, it's cracked nearly half way around the tube. The crack will only grow slowly up to a point - eventually there won't be enough material to hold the front on and it'll break suddenly. This is a common cause of "just riding along" breakages - the damage was already there, the frames just happen to let go during fairly innocuous riding.
It's not welding or heat that cracks frames, it's using them ;-)
