• Abstract:
  The purpose of this work was to study the effect of (1) marking parameters – head speed (writing) and amperage (current) – on the plasma notch and heat affected zone (HAZ) depth and (2) the plasma notch and HAZ depth on the mechanical properties of 50W weathering bridge steel. Both marking parameters will be altered, resulting in varying plasma notch and HAZ depth. A relationship between plasma marking parameters and notch HAZ depth will be revealed, as well as its consequent effects on the fatigue life. The overall goal of this study was to provide guidelines for marking bridge steels for future standardization and implementation.
