Carbon Equivalent provides an indication of a steel’s susceptibility to heat-affected zone (HAZ) issues during welding. Steels with higher CE values are more prone to hardening and cracking, making them less weldable without careful control of welding parameters.
23 gru 2020 · The carbon equivalent (CE) is used to understand how the alloys mentioned above affect the hardness of the steel being welded. There are many different CE formulas, but the two most commonly used are those accepted by the American Welding Society and the International Institute of Welding.
In welding, carbon equivalent (CE) calculations are used to predict heat affected zone (HAZ) hardenability in steels. These CE equations can be used to establish criteria to predict cold-cracking, as they can predict maximum hardness.
There are numerous formulas for describing the carbon equivalent, in which the individual alloying elements are weighted differently. The carbon equivalent can thus be generally understood as a measure of a material's tendency to cold cracking depending on its chemical composition.
19 lis 2019 · LIBS technology (Laser Induced Breakdown Spectroscopy) can be utilized to help accurately and repeatedly capture carbon content as well as automatically calculate carbon equivalency using a prescribed formula via pseudo element feature.
History, uses, and equations for a range of Carbon Equivalent calculations, as used to assess steel weldability, are presented.
