Quality tools include Pareto charts, fishbone diagrams, control charts, scatter diagrams, and histograms.

• Pareto charts: used to prioritize issues based on frequency or impact

• Fishbone diagrams: used to identify root causes of problems

• Control charts: used to monitor process variation over time

• Scatter diagrams: used to show the relationship between two variables

• Histograms: used to display the distribution of data

PPAP is used to ensure that suppliers meet quality standards and specifications before production begins.

• PPAP helps to prevent quality issues by ensuring suppliers have processes in place to meet specifications

• It provides a standardized way for suppliers to communicate their capabilities and quality control measures

SPC stands for Statistical Process Control, a method used to monitor and control processes to ensure they are operating efficiently.

• SPC involves collecting and analyzing data to understand variation in a process

• It helps identify when a process is out of control and needs adjustment

• Common tools used in SPC include control charts, histograms, and Pareto charts

Measurement system analysis is a method used to assess the variation in measurement processes and ensure accuracy and reliability.

• Measurement system analysis evaluates the capability of a measurement system to provide accurate and reliable results.

• It involves assessing the precision, accuracy, repeatability, reproducibility, and stability of the measurement system.

• Common methods used in measurement system analysis incl...read more

Types of welding include MIG, TIG, stick, and flux-cored welding.

• MIG welding uses a wire electrode and shielding gas.

• TIG welding uses a tungsten electrode and inert gas.

• Stick welding uses a consumable electrode coated in flux.

• Flux-cored welding uses a tubular wire filled with flux.

• Other types include spot welding, laser welding, and resistance welding.
