CO2 shielding gas on FCAW - Answer widely used, low cost, deep arc penetration, relatively inert at room temp., dissociates at arc temps., allow for oxidation in the weld pool. Textbook: 6.5-1 - 6.5-4 Ar-CO2 shielding gas for FCAW - Answer allows for greater oxidation resistance, most common ratio is: 75% Ar, 25% CO2, generally gives welds higher tensile & yield strengths than welds of 100% CO2, spray mode mixture, Excessive amounts of filler materials (Mn, Si, Al) will change mech. propertie...
