The butt weld that joins the 2 oval pieces of the rack at the center is horrible.  Its a single pass butt weld on only 1 side of the joint.  It does not have full penetration and does not go from end to end.  it makes me worry about the strength and reliability of the rack.  If that weld breaks the whole rack would fall.  Also, i didn't see a spec for weight limit of the rack.  This is important.
