Abstract
To measure the amount of free nitrogen in a welding run (low carbon steel deposited by submerged arc) the internal friction and low frequency elastic module techniques are used, based on the Snoek relaxation effect associated with the displacement of the interstitial solute. Cylindrical samples are activated by means of oscillating charges, keeping the range of movement constant during the heating and cooling cycles, after which internal friction peaks and steppings in the elastic module occur. In the case of welding deposits, the internal friction spectrum is complex, so that squared minimum adjustment of experimental spectrum is used, through a series of perfect Debye peaks. The identification of peaks allows a qualitative evaluation of the free nitrogen. The quantitative evaluation requires a calibration using test pieces subject to solubilization. (Author)
