THE COMPARATIVE ANALYSIS OF GAS EMISSIONS DURING MECHANIZED MAG WELDING USING CORED WIRES MIHAILESCU Danut1, a, FRINCU Octavian2, b and GHEONEA Marius Corneliu3, c 1“Dunarea de Jos” University of Galati, Faculty of Mechanical Engineering, Domneasca St. 111, Galati, Romania 2Moody International - Intertek Abu Dhabi, PO Box 47754, United Arab Emirates 3“Dunarea de Jos” University of Galati, Faculty of Mechanical Engineering, Domneasca St. 111, Galati, Romania adanut.mihailescu@ugal.ro, boctavian.frincu@gmail.com, cmarius_gheonea@yahoo.com Keywords: gas emissions, MAG welding, cored wires, shielding gas, shielding gas mixture Abstract: The use of cored wire - shielding gas (gas mixture) pair, during mechanized Metal Active Gas - MAG welding, leads to the formation of gas emissions (CO2, CO, NOx, NO, O3 etc) which is harmful for the welder’s health.
International research was conducted upon MAG welding with CO2 shielding gas and Ar-CO2, as well as Ar-CO2-O2 shielding mixtures, and different solid, flux cored, and self-shielded wires.

The improved mechanical properties and the increase in wear resistance is given by the ceramic particle content [1,2].
Particle reinforced materials contain approximately equidistant reinforcing particles with a ratio smaller than 5%, usually ceramic ones (Al2O3, SiC, Gr) [3,4].

The slenderness ratio is up to 31.6 and the ceramic roller is easy to be broken during heating.
At the same time, the CAM is actively expanding the usage of hot stamping technology in engineering machinery, container manufacturing and other industry applications to achieve lightweight of related products.

Since the beginning of last century, most drilling bits were fabricated with a composite of hard ceramic particles of tungsten carbide (WC) bound with a metallic cobalt phase (Co) [1,2].
Part of this desirable engineering performance is dire to the plastic and thermal stable behavior of the Co.
End particular, the doping of a Cu alloy, by Ti causes the formation of hardened micro layers around the ceramic particles.
