WebIn aluminium castings, hydrogen is the only gas that dissolves in significant quantity, which can result in hydrogen gas porosity. For casting that are a few kilograms in weight the pores are usually 0.01 to 0.5 mm (0.00039 to 0.01969 in) in size. In larger casting, they can be up to a millimetre (0.040 in) in diameter.

Web6.07.2.5.1 Oxide Inclusions. Oxide 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). For example, in laser beam welding (LBW) process, the keyhole ...
