Scanning electron microscopy was carried out on surfaces of aluminum alloy plates A5083 P-0 and A1070 P-0 mechanically, chemically and thermally pre-treated to explain a role of the surface pre-treatment in blow hole formation in welds. Other factors such as the arc phenomenon, thickness and composite structure of surface oxide film etc. should be taken into consideration. Residual chemical reaction products "smatt", thick oxide films formed at high temperatures and sometimes wire brushing can cause a hydrogen source to form blow holes in welding.
