Published articles show the
average MIG welder uses over 5 times the amount of shielding gas
necessary (See References).
Much of this is due to the large excess gas flow surge that occurs at the weld start. This
excess flow not only wastes gas it
also pulls moisture laden air into the gas stream. This entrained air produces
inferior weld starts with excess spatter and possibly weld porosity.
Some gas waste may also be due to welders setting excess flow rates which can
also pull air into the shielding gas stream for the weld duration. |

 When using Carbon Dioxide (CO2)
shielding wasting 80% of the amount of gas used unnecessarily increases this "greenhouse gas"
escaping into the atmosphere.
Excess CO2 in the atmosphere is attributed to assisting global warming. For
one average
industrial MIG welder the excess over what is needed can exceed 140,000 ft3
(CF) of CO2
per year.
That's about 17,000 pounds (8.5 tons!) of wasted CO2
per welder per year!

 How
Much CO2 is in the Air?
Currently
there is about 0.035% in the air. That compares to 0.025 to 0.028%
estimated to exist before the Industrial Revolution. Therefore if we
wanted to go back to Pre-Industrial Revolution Levels we'd only have to
remove 0.01% from the air! An interesting technical paper by Lacker,
Grimes, Ziock indicates one can capture CO2
and absorb it in chemicals such as Calcium Hydroxide for about $0.001/CF.
Since the cost for welding is about $0.02/CF sounds like a viable option.
They show a device like a cooling tower that can be used to capture air very
inexpensively! Certainly power plants could capture it before it was
diluted in the air.
The desirability of doing any of this or defining
the magnitude of the problem versus other causes for weather changes is well
outside my technical field so I can't intelligently comment. However
it makes sense to save 50 to 60% of the CO2
shielding gas being used (wasted) when welding just as a matter of economics!
It is also very inexpensive with payback measured in months by using our Gas
Saver System! You'll also get better weld starts by avoiding pulling
moisture laden air into the weld start area! |

Using Argon Shielding?
When using Argon
shielding gas your still adding to "Greenhouse Gases."
Production of Argon is very energy intensive. Significant power is
required to compress and liquefy air to extract the ~ 0.9% Argon it
contains. It fact it can not be done economically unless producers can
sell the Nitrogen and Oxygen which are 99% of the air!
Quoting a
Universal Industrial Gases, Inc internet source; "The
cost of electricity is the largest single operating cost incurred in air
separation plants. Power cost is usually between one third and two thirds
of the total cost of producing gas and liquid products. Large liquid plants
may consume tens of thousands of Kilowatts per hour."
Currently 71% of the US production of electricity is being produced by burning coal,
oil or
natural gas with CO2 a product of this combustion (See
Pie Chart.) |
|
 Another
significant fossil fuel energy use occurs when the shielding gas is
transported in trucks to a fabricator. To deliver 300 to 500 cubic
feet of shielding gas, a 150 pound steel cylinder must often be transported in a
truck using gasoline or diesel fuel. The empty cylinder must also be
returned for filling.
Bulk gas is more efficient to transport (113 CF Argon/gallon) but still requires the use of a
truck powered currently powered by carbon based fuels. |

 In
addition to significant Argon price increases, now Helium is in short supply. Seems
a Helium plant due to come on stream in Algeria is delayed. US Sources
are also
having difficulties keeping up with demand. Unlike Argon which is ~ 0.9% of the air, Helium is
a limited world wide resource. Most of the Helium in the "Universe"
was created during the "Big Bang" with a small amount generated in stars!
We obtain Helium as a by product in natural gas production. Why
not extract it from the air where all that is used ultimately goes?
Because it is so light it escapes the earths atmosphere and goes into outer
space! Shortages and allocation are predicted.
If your using any amount of Helium for welding the payback for our Gas Saver System is a
"Just Do It" no brainer!
See what a Praxair Executive told a industrial
gases and welding distributor organization about the Helium shortage. |
