Simplified Approach to Estimate Shielding Gas Waste - -

How Long Can
You Wait to Reduce Your Shielding Gas Waste??
Recent price increases of up to 40%
have been implemented by the major gas producers. Delivery costs have
also increased significantly. It's time to reduce your use while
improving weld quality!
|
The table below provides a way to make an estimate of
shielding gas waste. The data needed is simple to obtain from
purchasing or your supplier of wire and shielding gas.
 Use purchases over a period of 6 months to a year to avoid
introducing errors due to variable amounts of inventory.
Notes: 1) If your using CO2
it probably was purchased in pounds. You'll need cubic feet (CF) in the
calculations; there are 8.74 CF per pound of CO2;
2) Argon is usually sold in CF or in 100 CF- if you are purchasing
Argon in Liquid form you may be purchasing it in gallons. If so there
are 113 CF of Argon gas when measured at 70 deg F and 1 atmosphere in each
liquid gallon; 3) If the welding wire purchase records are only kept in
dollars, you'll need the cost per pound. If needed, ask your supplier,
they keep the data in a form that you can use directly.

Compare the typical values in the above table with your usage.
Example; You purchased 46,000 lbs of 0.045
solid wire in the past 6 months and during the same period 610,000 CF of
Argon and CO2
combined:
Multiple the value from the far right column in the above table times the
wire purchase amount; 5.0 CF/ 1 pound X 46,000 lb
of wire purchased = 230,000 CF of gas you should have purchased.
But you purchased 610,000 CF of
gas. Therefore 610,000 – 230,000 = 380,000 CF was wasted or 380,000 Wasted
/ 610,000 Purchased = 62% Gas Wasted!
If you use several types of wire, treat each individually and add the
total gas requirements.
We have found this waste percentage to be typical
with some locations wasting significantly more!
