these, the welding cost per foot is $.2249 ($.738 per meter). As
can be seen, labor and overhead are 83% of the total. One
item worthy of note is that in any calculation of welding cost per foot(m) of
weld, the shielding gas cost in Mig welding
is never more than 10% of the total cost of the weld, whether pure CO2
or more expensive argon mixture is
used. Both gases have their technical advantages and disadvantages. The
choice is based on which affords the greatest
overall advantage in your application. Even on a 60% duty cycle, toe
total gas cost per foot of weldment is between $.01 and
$.025 ($.03 - $.082/meter). *Cost
