Non-destructive testing is a method of testing materials without damaging them.

• NDT is used to detect defects or irregularities in materials or structures.

• It is commonly used in industries such as aerospace, automotive, and construction.

• Examples of NDT methods include ultrasonic testing, radiography, and magnetic particle inspection.

• NDT helps ensure the safety and reliability of products and structures.

• It can also save time and money by identifying issues before they become ma...read more

Magnetic particle testing is a non-destructive testing method used to detect surface and slightly subsurface discontinuities in ferromagnetic materials.

• A magnetic field is applied to the material being tested

• Iron oxide particles are then applied to the surface

• The particles will accumulate at areas of magnetic flux leakage caused by discontinuities

• The particles can be seen under UV light or with a black light

• Commonly used in the aerospace, automotive, and manufacturing industr...read more

Vernier caliper least count is the smallest measurement that can be read on the scale of the caliper.

• The least count of a vernier caliper is typically 0.02 mm or 0.001 inches.

• It is determined by dividing the smallest division on the main scale by the total number of divisions on the vernier scale.

• For example, if the main scale has divisions of 1 mm and the vernier scale has 50 divisions, the least count would be 0.02 mm.

Welding defects can compromise the strength and integrity of welded joints.

• Welding defects can occur due to various factors such as improper welding technique, inadequate preparation, or faulty equipment.

• Common welding defects include porosity, lack of fusion, undercutting, and excessive spatter.

• Porosity refers to the presence of small holes or voids in the weld metal, which can weaken the joint.

• Lack of fusion occurs when the weld metal fails to fuse completely with the base ...read more

The formula for spring rate is the amount of force required to compress a spring by a certain distance.

• Spring rate = Force / Distance

• The unit of spring rate is N/m or lbs/in

• The spring rate is dependent on the material and geometry of the spring

• The formula can be used to calculate the spring rate of compression, extension, and torsion springs

Gauges are instruments used to measure and display various physical quantities. Some common gauges are:

• Vernier caliper

• Micrometer

• Dial indicator

• Height gauge

• Thread gauge

The 7 QC tools are a set of basic statistical tools used for quality control and improvement in manufacturing processes.

• Check sheet: Used to collect and analyze data in a systematic manner.

• Histogram: Represents data distribution visually to identify patterns and trends.

• Pareto chart: Helps prioritize issues by showing the most significant factors affecting quality.

• Cause and effect diagram (Fishbone diagram): Identifies root causes of problems.

• Scatter diagram: Shows the relatio...read more

GD&T symbols are geometric dimensioning and tolerancing symbols used to define the geometry of parts and specify allowable variations.

• GD&T symbols are used to communicate design requirements for parts in engineering drawings.

• They include symbols for features like flatness, perpendicularity, concentricity, and more.

• GD&T symbols help ensure that parts are manufactured to the correct dimensions and tolerances.

• Examples of GD&T symbols include ⊥ for perpendicularity, ⌀ for diamete...read more
