An Electrochemical Evaluation on the Corrosion of Weld Zone in Cold Arc Welding Process of the Cast Iron
- 발행 : 2005.06.23
초록
Variation of hardness and corrosion potential of welding zone was investigated when cold arc welding of cast iron was carried out with a parameter of Ni electrode. Hardness of HAZ was the highest compared to other welding zone. And corrosion potential of HAZ was also more negative value than other welding zone. However there was not a proportional relation between hardness and corrosion potential. Local corrosion of HAZ was clearly appeared than other welding zone by small anode and large cathode in seal water solution.
