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

Quality is the measure of excellence or superiority of a product or service.

• Quality is meeting or exceeding customer expectations.

• It involves consistency, reliability, and durability.

• Quality is achieved through proper planning, control, and improvement processes.

• Examples include defect-free products, high customer satisfaction, and meeting industry standards.

• 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
