　　lifting and liftingThe effectiveness of ultrasonic detection is often affected by factors such as hook grains, ultrasonic attenuation and forest-like echoes, rough surface, complex morphology and unfavorable orientation of certain defects. Therefore, when performing ultrasonic flaw detection, the hook should be heat treated (i.e. normalizing + tempering) to refine uniform tissue, reduce areas and blind spots that cannot be reached in sound beam scanning, and evaluate the size and type of defects more accurately, and other effective methods are needed to assist in judgment.

　　The straight probe uses a contact surface to scan the cylindrical surface of the hook handle, the hook cavity, the outer arc surface of the hook cavity and the side surface of the hook head perpendicular to the forging flow line.

　　The inclined probe is scanned parallelly along both sides of the forged streamline, the inclined probe is scanned inclined with the forged easily folded parts, and the inner surface of the hook cavity is perpendicular.

　　For parts that cannot be scanned due to the geometric shape of the forging, records and explanations should be made, and if necessary, both parties agree.

　　Due to the limitations of the shape of the lifting sling and ultrasonic flaw detection, different detection results can be obtained on different detection surfaces, and the positioning and quantitative analysis of defects is difficult. Generally, the hazardous cross-section and relatively serious defects of the position hook are used as the conclusion; defect qualitativeness In addition to evaluating defects from the aspects of production process, location, general direction and distribution of defects, ultrasonic flaw detection alone cannot be used to characterize defects. For important occasions and when using hooks, defects should be characterized by other effective methods.

　　The above is some introduction to the content that should be paid attention to when detecting non-destructive flaws of lifting and spreaders. You can learn about it.
