An investigation was carried out about the influence of pulse conditions of MAG welding (CO2, Ar+20CO2, Ar-O2, Ar+2.4%O2+20%CO2) upon spatter loss and porosity. And the test results are as follows.<br>(1) Pulse welding with conditions of Iav=250A, Ip=500A N=300Hz, in Ar+2.4%O2+20%CO2, is found to decrease the spatter loss dramatically.<br>(2) Pulse welding with condition of Iav=250A Ip=500A N=300Hz, in Ar+2.4%O2+20%CO2, is found to decrease the blowholes in weld metal to zero per 10cm bead.<br>(3) Welding with pulse condition of Iav=250A, Ip=500A, N=250Hz is found to increase the wire melting rate to 1.5 times higher than the welding with no pulse.<br>(4) Suitable wire composition for no blowhole and no spatter in MAG welding is DD50S; 0.05C-0.5Si-1.3Mn-0.05Ti.<br>(5) Applying the pulse welding to the primer coated plates, it is found that the new inorganic zinc rich primer coated plates can be welding with condition of Iav=250, Ip=500A, N=300Hz, Ar+2.4%O2+20%CO2.
