USE OF WELDING SHIELDING GAS MIXTURES IN AUTOMOTIVE WELDING PROCESSES

Richard MOLNAR, Anamaria FEIER, Felicia BANCIU, Margareta COTEAȚĂ

Abstract


The paper will present a review of the use of shielding gases used for welding in the automotive industry and the main problems caused by the effect of shielding gases. The welding technologies in which some mixtures of shielding gases are used allows the improvement the fatigue and corrosion resistance characteristics required in welded joints of automotive body parts, as well as an efficiency booster in the production process. Shielded arc welding with low CO2 concentration shielding gases, Plasma-Arc HybridTM welding and hybrid laser arc welding will be highlighted in this paper and some methods to improve welding parameters by different shielding gas mixtures will be presented.
