Investigation of Effects of Mig Welding on Corrosion Behaviour of AISI 1010 Carbon Steel

This paper presents the corrosion behaviour of welded low carbon steel at different welding voltages and filler materials. The welding process was conducted on butt joint specimens using the metal inert gas (MIG) technique at a welding voltage range of 19 to 21 V with 1 V interval, and the filler m...
