Didn't look like braze to me either. Lotsa folk don't like welding on on something like this as you are very likely to uncover inclusions and other imperfections that may require additional time and effort to correct. Looks to me like the root has been reshaped and my concern would be that the extraction cam would need to be rebuilt and rehardened but the OP has chosen not to post additional pics. So, good luck to him getting this sorted.
