WebOxide inclusion during the welding process is mainly attributed to the strong affinity of the WMs toward oxygen. Surface oxides are formed in three stages: (1) oxygen chemisorption, (2) formation of the oxide layer, and (3) thickening of the oxide (9). WebInclusions are solid particles entrapped in the casting whereas porosity is the result of gas entrapment in the solidifying metal. On an X-ray, inclusions show as dark, jagged asymmetric shapes whereas porosity takes the form of dark spots or specks. Reducing the risk of inclusions in sand casting
