This study was carried out to investigate the effect of welding parameters such as shielding gas compositions welding voltage and welding current on the pore formation in the weld beads of galvanized steel pipes produced with gas metal arc welding. The porosity was evaluated and rated by metallography and radiographic test in terms of weight percentage, number and distribution of pores in weld beads. The porosity increased with increasing welding voltage and current, in which Ar gas produced the most porosity while Ar+5%O₂ generated the least porosity. It was found that the porosity could be reduced by selection of the proper gas mixture composition such as Ar+5%O2 and Ar+10%CO₂ and by using current (130~150A) and voltage(16~20V).
