Re: Welding glasses
If by "welding glasses" you mean basic goggles, they're probably not protective enough to save you if a laser hits your eye directly.
If you mean like an arc welding visor - then sure, that would solve one problem. You wouldn't be blinded by a laser pointer. However, you also wouldn't be able to see a bloody thing in the cockpit, or much outside it unless the sun happened to be straight in front of you. So, kinda self-defeating.
