I don't think it's difficulty in verifying, it's just not the right tool for the job in a lot cases on an airplane. Aircraft don't use much steel, and aluminum welds typically have a heat affected zone (HAZ) adjacent to the weld which is weaker and more prone to fatigue cracking. For this reason aluminum is often riveted or bolted.
