Abstract

In situ Scanning Vibrating Electrode Technique and time lapse photography were used to study the galvanic corrosion of high strength low alloy (HSLA) steel, laser welded to hot stamped ultra high strength steel (UHSS) in 0.017 M NaCl. Samples of HSLA welded to UHSS exhibited corrosion focused on the...
