Abstract
A method for determining the element concentration in electron beam melting is used for the continous measurement during the melting process especially for melting alloys. According to the invention, the X-radiation generated during melting is utilized by concurrently measuring the intensity of the characteristic radiation of the element to be determined and the intensity of another portion of the X-ray spectrum from the same location of the melt. The quotient of both measurands then is a function of the concentration of the element to be determined.
