What''s up with helium for welding applications?
Lyttle pointed out the use of a CO 2 laser for welding applications as an example. Traditionally, helium is used as a shielding gas in CO 2 laser welding, but it is supplied in a less-than-efficient manner to the area. In the simplest of descriptions, a copper tube simply floods the welding area with helium when the laser is engaged.
