Manufacturing method of internal crack defect testing plate for non-destructive testing teaching
TL;DR: In this article, a manufacturing method of an internal crack defect testing plate for non-destructive testing teaching is presented, in which the welded joint cold crack generation mechanism in the welding process is utilized, the high-constraint testing plate butt joint mode is adopted, a high-carbon-equivalent welding material is used, normal-temperature welding is conducted and supplemented by application of the forced rapid cooling measure after welding is accomplished, a product is placed for 24 hours, and therefore a welded joints internal crack which meets the requirements for the designed crack position,
