Description

technical field [0001] The invention relates to the field of residual stress measurement, in particular to a deep automatic electrolytic corrosion system and method for measuring residual stress. [0002] Background technique; [0003] When measuring the residual stress distribution of a metal workpiece along the depth direction, electrolytic corrosion is required layer by layer along the depth direction. Traditional electrolytic corrosion is currently mainly operated manually, and its electrolytic corrosion has the following common disadvantages: 1) When manually operating each electrolytic corrosion process, it cannot accurately control the corrosion time of electrolytic corrosion and the amount of electrolytic solution, resulting in each corrosion The depth cannot be precisely controlled; 2) The depth of electrolytic corrosion is measured by a vernier caliper, which has a large error and affects the experimental results; 3) Simple repetitive work makes the operator prone t...
