You might not want to hear this but you asked.
Welding is just like painting or many other procedures. The
final weld is only as good as the preparation, just as the
final paint job is only as good as the work to bring it up to
the point of laying down the paint.
If the area to be welded wasn't cleaned and prepared properly
then you shouldn't expect it to be a solid joint.
Had it been me I would have told you this and explained that it
had to be prepped correctly before I would weld it.
Try to imagine what a performance would sound like if none of the
musicians spent hours preparing before they went on stage for their
three minute performance.
My opinion, both of you were in the wrong. You for not doing
your homework and him for laying down a bead that he knew may
be questionable.
