Welding Helmet (Fallout: New Vegas)

The welding helmet is a piece of headwear $$

Gameplay
It provides a Damage Threshold of 2 and can be repaired with raider helmets.

Locations
It is worn by four Boomer welders. These welders only appear after completing Volare!, whereupon they are found working on the B-29. They are on high scaffolding and are hard to reach. If they are killed, they may fall off the scaffolding to the floor, where one can loot them. The Boomer welders respawn after some time.
