An apparatus and method are available for detecting the presence of inert gas in an enclosure isolating one side of selected weld structures being joined during welding operation. The system and method include using an inert gas detector relying upon an electric filament positioned in a separate containment connected to the first containment in order to determined whether the required purity level of inert gas has been achieved in the weld enclosure.
