This App is for welding engineers, technicians and experts. You found the quality levels for imperfections for welds (Aluminium) in the ISO 10042. This App calculated the value for one concretely weld. Select the weld, then input the geometry of the weld, then select the imperfections. The result for this weld is displayed. You can now the result compared with the measurement. The weld is OK or not. Version 1.0
