If the manual measurement process of the Agt meets the standard requirement, the distance between the Agt and the fracture is 50mm or 2d (the larger is selected), and the distance between the Agt and the holding section is more than 20mm or d (the larger is selected). Then the total length of the mark gauge length is at least 400mm or more to ensure that the test is effective. If a grid pitch interval of 20mm is selected, at least 20 points are marked, and the bottle neck is marked manually.
(2) In the metallurgical industry, the large number of stretching detections is completed by all manual marking methods or mechanical single-strip dotting methods at present, the manual marking method has large manual errors, particularly marking distance marking below 50mm intervals is difficult to meet the requirement of +/-1% marking error manually, and large manpower and time are consumed for marking so as to meet the requirement of +/-1% marking distance marking, so that the method becomes another bottleneck of low stretching detection efficiency.
(3) The manual gauge length marking or mechanical single dotting method cannot control the marking depth, and the industrial wire tensile sample with strong crack sensitivity can be broken to the marking position to cause uncontrollable conditions such as experiment failure and the like.
