Using helium gas when performing a Heliarc weld is done to shield the area which is being welded. This was vital in order to keep the electrode and the arc tightly compressed into one point of contact. This will create an immense amount of heat, which the welder will use to create strong seams.
In some cases, a filler will be used to fill in any spaces found between the metals which are being welded. Heliarc welding equipment since the 1940s has come a long way, this is due to the leaps and bounds in technology, which means fillers are not necessary anymore. Because of this, TIG welding is done in a slower and more exact process than many other types of welding. However, this method will take some welders time to properly learn.
