Macroscopic Metallographic Analysis
Purposes:
To evaluate whether there is a hole and inclusions in die casting and welding line; to decide the organization direction of die casting; whether there exits obvious flaws of no penetration in weld line.
Applications:
Cast iron, steel, nonferrous metals, welding parts and so on.
Tested Flow:
Sampling→Cleaning→Inlaying→Grinding→Polishing→Etching→Observeing
Reference Standard:
GB/T 3246.2-2000 Inspection method for structure of wrought aluminium and aluminium alloys products—inspection method for macrostructure
GB/T 226-1991 Etch test for macrostructure and defect of steels
