Chromium is a weak deoxidizer. In this report chromium have been used as single deoxidizer in the straight lime basic type electrodes. The weld metals have been attained by usual hand arc welding. Inclusions of the weld metals was extracted by carbon evaporated replica. Thus extracted inclusions were investigated by the electron microscope. The deoxidation products was proved to be chromite spinel. (FeO.Cr2O3) And its size are usually larger than several microns. Chromite inclusions have beautiful angular shaped type.
