Comparison of the Corrosion Resistances of Welded and Brazed Joints Made of Galvanized 08Yu Steel

摘要

We analyze the corrosion resistance of permanent joints of 08Yu steel prepared by different methods: metal active gas welding, tungsten inert gas brazing, plasma brazing, and brazing with the use of the cold metal transfer (CMT) process. It is established that brazing by using the CMT process provides the highest electrochemical homogeneity of the permanent joint, as well as the highest corrosion resistance of the brazed joint under the investigated conditions.
