Multi-element quantitative analysis
ELANIK
Elemental Laser Analyzer
ELANIK - METAL ANALYZER. CARBON ANALYSIS IN STEELS AND CAST IRONS.
One of the important applications of ELANIK is the analysis of carbon concentration in steel and cast iron.
Steel is the most common alloy, and carbon concentration has a significant impact on its properties (ductility, strength and hardness, weldability, etc.).
The determination of carbon concentration is very important when using steel in industry. This is one of the most relevant and complex tasks of elemental express analysis for portable devices.
Hand-held X-ray fluorescence analyzers cannot measure carbon. Analysis of carbon using optical emission spectrometers requires the use of argon, careful preparation for measurement and highly qualified specialists. In addition, they are bulky and almost impossible to use in hard to reach places or at heights.
ELANIK is the first hand-held analyzer measuring the concentration of carbon in metals and alloys directly in the air. Other elements of the alloy are analyzed at the same time.
One of the important tasks is to measure carbon in unalloyed steels, since more than 80% of metal products in the world are produced from them. Due to the absence of alloying elements, it is impossible to determine the grade indirectly, by the content of other elements, which are sometimes used by XRF in the analysis of alloyed steels.
CARBON EQUIVALENT (CE) AND WELDABILITY OF STEELS
Weldability is one of the most important properties of structural steels, since most metal structures are welded. The chemical composition of steel has a significant effect on its weldability. One of the most important technological indicators of weldability is the carbon equivalent (CE). It allows you to evaluate the combined effect of carbon and other elements contained in steel on its weldability, and helps to choose the optimal welding technology and mode.
ELANIK performs multielement quantitative analysis (including C, Mn, Cr, Si, Mo, V, Cu, Ni, etc.) - so, for the convenience of our customers using ELANIK during welding or heat treatment, we introduced the calculation of the carbon equivalent for low alloyed and medium alloyed steels (calculation formula can be chosen by the customer when ordering). CE is displayed on the screen of the device simultaneously with the chemical composition and allows you to immediately see the estimation of the weldability of steel.
The default is the Dearden and O'Neill formula recommended by the International Welding Institute (IIW) and the following scale for evaluating weldability:
Since LIBS metal analyzer ELANIK measures carbon, it makes it possible to distinguish between steel grades that differ only in carbon.
An important advantage of ELANIK is the possibility of conducting an estimation of CE “in the field”, right at the place of welding and the construction of metal structures, pipelines, etc.
