The utility model discloses a kind of billet macrographic inspection photo frame, including base platform, lifting adjusting device, mobile phone rack, annular light supplement lamp and resistance regulating switch;The base platform is horizontally arranged;The lifting adjusting device is vertically fixedly connected to the upper surface of the base platform;The mobile phone rack is fixedly installed in the top of the lifting adjusting device;The annular light supplement lamp is arranged around the outer periphery of the mobile phone rack;The resistance regulating switch is electrically connected with the annular light supplement lamp.The utility model avoids virtual image completely through rigid base+equipment clamping structure to eliminate shooting shake;Through coaxial annular LED light source, shadow and light spot are eliminated to realize uniform illumination without interference;Through scale ruler, multiple batches shooting height error is reduced to realize;Adjustable clamping arm is adapted to various shooting equipment, fixed clamp is compatible with different size samples, and compatibility is improved.

The invention belongs to the technical field of high-temperature alloy low-power machining and defect identification, and particularly relates to a machining and corrosion method for high-temperature alloy low-power inspection, which comprises the following steps: S1, after a high-temperature alloy finished product bar is forged / rolled and formed, turning the outer surface, removing surface oxide skin and cracks, sawing a sample piece, and carrying out high-temperature alloy low-power inspection; then carrying out standard heat treatment on the sample piece to remove stress so as to reduce the stress before processing and obtain a macroscopic sample; s2, turning the macroscopic sample on a lathe according to specific process parameters until the surface roughness Ra is less than or equal to 1.0 mu m; and S3, spraying a cleaning solution to the surface of the turned macroscopic sample to remove oil stains, then blow-drying the macroscopic sample, putting the macroscopic sample into special corrosion equipment, corroding the macroscopic sample by adopting a corrosive solution, and washing and blow-drying the surface after corrosion is finished. According to the method, the processing and corrosion quality of the macroscopic sample for high-temperature alloy detection is improved, meanwhile, the production period is shortened, and the cost is saved.
