When pure copper electrode wire is used, a excessive welding present results in good surface appearance and deep penetration, however high porosity in the weld metallic. Possibility of a diversified flux formulation, related to excessive deposition charges, has been a bonus in welding processes by applying tubular wires, especially steel cored arc welding (MCAW), characterized by metallic powders in the flux. However, the presence of an solely metallic flux may not establish optimum welding conditions, requiring the addition of different ingredients within the flux. The results of welding conditions, nitrogen proportion in the shielding gasoline and titanium content of the electrode wire on porosity and microstructure of the weld steel have been systematically examined. The results of welding conditions, N2% in the shielding fuel and titanium content of the electrode wire on the porosity and the microstructure of the weld metallic had been systematically examined.

N2 – Pure copper plates had been welded with pure copper and Cu-Ti alloy electrode wires utilizing Ar-N//2 fuel shieldings. The fractional space of the secondary part within the weld metal increases with N2% in the shielding fuel and titanium content of the electrode wire. The fractional area of the secondary phase in the weld steel will increase with N//2% in the shielding gas and titanium content material of the electrode wire. 2) As N2% in the shielding gasoline will increase, the porosity of the weld steel increases. 3) The nitrogen content of the weld steel increases with N2% in the shielding gasoline. The nitrogen content material of weld metallic increases with N//2% within the shielding gas. The porosity of weld steel will increase with N//2% within the shielding gas. The results are as follows: (1) Using copper electrode wire, the weld metal shows better floor look, much less porosity and deeper penetration with increase of the welding current. However, the tendency turns into very slight within the case of using Cu-Ti electrode wire. AB – Pure copper plates have been welded with pure copper and Cu-Ti alloy electrode wires utilizing Ar-N//2 fuel shieldings.
