The corrosion of welds in ice-breaking ships - a review / J.B. Gilmour. : M38-13/80-14E-PDF

"Literature related to the corrosion at the welds of icebreaking ships has been reviewed. Two distinct types of corrosion - weld metal attack and weld heat-affected zone attack - are described. Both types of attack are the result of small differences in corrosion potential between the corroding metal and the hull plate. The use of welding electrodes containing copper and nickel will eliminate weld metal corrosion and special hull steels are available that are claimed to reduce heat affected zone attack. A research project to assist the Canadian marine industry to minimize this problem is proposed"--Abstract, p. i.
