What is Steel Plate Lamellar Tearing?
Steel plate lamellar tearing is a serious issue in the field of steel structures. It occurs mainly due to the presence of inclusions in the steel plate and the high restraint during welding. When a steel plate is being welded, the shrinkage forces generated can cause the lamellar tearing. This is because the non - metallic inclusions, like sulfides and oxides, are arranged in a laminar pattern in the steel plate. These inclusions can act as weak planes.
For example, in a large - scale construction project where thick steel plates are used for building frames. If proper precautions are not taken during welding, lamellar tearing can happen. The tearing can lead to the weakening of the overall structure and may even cause structural failure in extreme cases.
How to Detect Steel Plate Lamellar Tearing?
There are several methods to detect steel plate lamellar tearing. One common method is ultrasonic testing. Ultrasonic waves can penetrate the steel plate and detect any discontinuities or flaws that may indicate lamellar tearing. Another method is magnetic particle inspection. This method is useful for detecting surface - breaking cracks which may be related to lamellar tearing.
In a manufacturing plant, when inspecting a batch of steel plates, technicians may first use visual inspection to look for any obvious signs of tearing or distortion on the surface of the plates. Then, they will likely follow up with more detailed non - destructive testing methods like ultrasonic testing to ensure the integrity of the plates.
