FAQ
What is the purpose of plate thickness testing?
Answer: To detect cracks or defects within metal materials or components. Common testing methods include X-ray testing, ultrasonic testing, magnetic particle testing, penetrant testing, eddy current testing, gamma ray testing, fluorescent testing, and dye testing. Physical testing is nondestructive testing without chemical changes.
Nondestructive testing is a testing method that examines the surface and internal quality of the component being inspected without damaging the workpiece or the raw material.

Detecting cracks or defects within metal materials or components without damaging the substrate is crucial for ensuring the integrity of steel plates subjected to varying loads, such as those found in high-rise bridges, and steel materials with specialized loads, such as rails. Steel plates that fail testing may have internal defects that could cause cracks and propagate during welding. Severe internal defects, such as internal cracks, can initially damage the core of the plate, which then spreads throughout the entire thickness.
A572Gr50 steel plate has a density of 7.85 cubic meters.
