Problems solved by technology

[0003] The key step in the mesh strain analysis process is to print the grid on the surface of the board. Traditional ordinary carbon steel, galvanized sheet, aluminum sheet and other grid printing processes cannot effectively perform grid printing on aluminum-silicon plate coatings. , seriously affecting subsequent strain analysis
At present, there is no grid printing process specially suitable for aluminum-silicon coated plates, which can ensure effective and rapid analysis and measurement of subsequent grid strain data
