Low power is a name for a relatively high times, high times under the microscope as low in the normal size range can be enlarged 10 times the maximum observation, qualitative observation, macro morphology of macrostructure is observed in the low state of the times. Generally include the central loose, general loose, spindle type segregation, as well as a variety of macro defects can be exposed at low times.
Detection range: cast iron, steel, non-ferrous metal parts, welding parts, etc..
Principle: the low - fold defect inspection of metal is also called macro - test. It is a method of inspecting the surface of the metal, fracture surface, or macro structure and its defects with the naked eye or not more than ten times. Macro test in metal ingot casting, casting, forging, welding, rolling, heat treatment process, is a kind of important test methods.
The test method is simple and rapid, and can reflect the morphology and distribution characteristics of the microstructure and defects in the macroscopic area of the metal. So that people can correctly and comprehensively determine the quality of metal materials, in order to guide the production of scientific and rational use of materials. The basic work can also be made for the further optical gold and metallographic analysis. Macroscopic examination including macrostructure and defect inspection (including acid, sulfur India, tower turning and nondestructive wound control method) and fracture analysis
