Common Uses Of Helium Gas Adams Gas

Common Uses Of Helium Gas Adams Gas

Jun 09, 2017 One of heliums many industrial uses is to prevent chemicals from causing explosions, and this can be very helpful in welding. Helium does a similar job to argon in welding, in that it has a high heat transfer while its inert properties make for a great shielding gas. A high heat transfer usually correlates with faster welding with better beads.
