Corrosion study on welded mild steel in soil environment

This study was carried out to determine the corrosion behavior of welded mild steel in soil environment. The welding process was done by arc welding method at 70, 80, 90, 100 and 110 ampere. The corrosion behavior of welded mild steel was studied by immersion and typical electrochemical method. This...
