In tig welding a flux is sometimes needed because the inert gas cannot fully shield the molten metal. T or F?

Question

Is this answer true or false?

Answer 1

FALSE

Because the whole idea of TIG Welding is to shield the molten metal with an inert gas so that a flux WON'T have to be used.

According to Wikipedia: http://en.wikipedia.org/wiki/Tig_welding
"Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma."

Answer 2

false
