Periodic Table for Quality Engineers (QA/QC) 🎯
Visit weldfabworld.com
Because quality isn’t random — it’s systematic, structured, and scientific.
I created this Periodic Table for Quality Engineers to help professionals visualize the key concepts, tools, methods, and standards that drive excellence in Oil & Gas, Construction, Fabrication, and Energy sectors.
Each “element” represents a core competency every QA/QC professional should master 👇
📘 F-Series: Foundation
QF – Quality Fundamentals
SP – Specifications
DR – Drawings & Isometrics
CS – Codes & Standards
MT – Material Traceability
DM – Document Management
📏 I-Series: Inspection
VI – Visual Inspection
DI – Dimensional Inspection
FI – Fit-up Inspection
WI – Welding Inspection
PI – Painting/Coating Inspection
HT – Hydrostatic Testing
PT – Pneumatic Testing
RI – Receiving Inspection
🔧 W-Series: Welding & Fabrication
WPS – Welding Procedure Specification
PQR – Procedure Qualification Record
WPQ – Welder Qualification
PN – P-Number
FN – F-Number
AN – A-Number
FE – Filler Metal Selection
🧲 N-Series: NDT Methods
VT – Visual Testing
PT – Dye Penetrant Testing
MT – Magnetic Particle Testing
UT – Ultrasonic Testing
RT – Radiographic Testing
PA – Phased Array
ET – Eddy Current
HT – Hardness Testing
📚 S-Series: Standards & Codes
AS – ASME
AW – AWS
IS – ISO 9001
OH – ISO 45001
ENV – ISO 14001
API – American Petroleum Institute

📦 T-Series: Quality Tools
RCA – Root Cause Analysis
5W1H – Problem Solving
FMEA – Failure Mode & Effects Analysis
CP – Control Plan
QC7 – Seven Quality Tools

CAPA – Corrective & Preventive Action
📝 P-Series: Project Documentation
QAP – Quality Plan
ITP – Inspection & Test Plan
WMS – Work Method Statement
MS – Method Statement
RFI – Request for Inspection
NCR – Nonconformance Report
MIR – Material Inspection Request
RIR – Receiving Inspection Report
🏗 C-Series: Construction Quality
