Non-destructive testing of rivets in the system
According to the requirements of different sensitivity levels, select fluorescent penetrants with different sensitivity levels. The water-washed rivet penetration test has a lower cost and a faster detection speed, but the detection sensitivity is low, and wider and shallower defects are easily missed; the post-emulsion penetration test has high sensitivity and can detect wide and shallow defects, but the cost is higher.
Non-destructive testing of rivets in the system
(1) Non-destructive testing technology is applied to the production of rivets, which can detect defective products, reduce costs, improve manufacturing processes, and improve product quality.
(2) According to the manufacturing process and defect formation mechanism of rivets, it is generally preferred to set up a non-destructive testing process before the use of raw materials and surface treatment.
(3) According to the defect type, rivet characteristics and the applicability of the non-destructive testing method, the economical and efficient non-destructive testing method should be flexibly selected under the premise of ensuring the sensitivity
