Yes, some of our windows do. For instance our 100-LW3 and 100-LW5 have welding safety and laser safety components. Generally no though unless noted. Please let us know if there is anything else you may need.
As the video illustrates, laser welding can present more than one eye and face protection consideration. The laser radiation itself may be invisible while still hazardous, while the welding process can also produce intense visible light.
