QQI's (Quantitative Quality Indicators) are magnetic particle test pieces with artificial defects used to verify proper field direction and adequate field strength. QQI's are a valuable tool to be used to establish testing criteria with Multi-Directional 2-D and 3-D type testers and to increase productivity by minimizing magnetizing shots.

qqi试片 是带有人工缺陷的薄钢片, 使用时贴在被测工件表面, 通常用于验证工件表面的场强和方向。qqi试片有若干种不同型号, 它是在薄钢片表面蚀刻加工圆形和十字形细凹槽而制成, 可以提供各方向的磁场指示。制作试片的钢材料成分和蚀刻凹槽尺寸, 按照as 5371 ...

美国磁通量化品质试片（qqi）是带有人工缺陷的标准磁粉检测试片，用以确定磁场方向和相应的磁场强度，亦可用于平衡多向磁场，将磁化次数降至最低，以提高生产效率。

Standard QQI - CX-230 - Set of 5 Quantitative Quality Indicators (QQI) are magnetic particle test pieces with artificial defects used to verify field direction and relative strength. QQI's are also used to balance multi-directional fields and to increase productivity by minimizing magnetizing shots.

removed from both faces of the QQI using SKC-S, acetone, or a suitable solvent. The part and shim must be clean and dry before application. Place the QQI flawside-down in intimate contact with the part being investigated and securely fasten it down on all four sides. To attach the QQIs, use non-fluorescent tape (for

2019年8月22日 · Quantitative Quality Indicators (QQI) QQIs are artificial, flaw-notched shims that are attached to example parts and are commonly used to demonstrate both field strength and direction within a part. They come in several different configurations: etched in circular and cross shaped patterns along with varying flaw depths.

In this article, we define Magnetic Particle Inspection Flux Indicator Strips and Quantitative Quality Indicators (QQI) and give a user manual approach to find artificial flaw standards.

qqi有几种不同的型号，为薄钢垫片，具 有圆形和十字形的蚀刻图案，可在所有方向上提供指示。 根据标准AS 5371中规定，钢合金和槽口尺寸设计用于在将工件磁化到其中磁场

Quantitative Quality Indicators (QQI) are magnetic particle test pieces with artificial defects used to verify field direction and relative strength. QQI's are also used to balance multi-directional fields and to increase productivity by minimizing magnetizing shots. The QQI indicator shims are packaged in sets of five. UNI-DIRECTIONAL INSTRUCTIONS

• Quantitative Quality Indicators (QQI) are magnetic particle test pieces with arti cial defects used to verify eld direction and relative strength. • The slim nature of these shims enables them to conform to curved part surfaces, typically secured in place through the application of …
