Qualification is demonstrating skills, while certification is formal recognition of those skills.

A document detailing how a weld should be made, including techniques and materials used.

A record documenting the actual weld made and its results to verify the WPS.

A set of rules or guidelines governing welding practices and standards.

A level of quality or attainment in welding, often set by organizations.

Key frameworks like API Standard 1104, ASME Section IX, and AWS D1.1 used to guide welding processes.

Choosing appropriate guidelines for specific welding applications is crucial in fabrication.

The process of verifying that welders have the necessary skills through tests and documentation.

A detailed list of rules for a specific type of welding product.

A legal requirement statement for a specific classification of a weld.

Processes to ensure a product meets code requirements after fabrication.

Code for welding pipelines published by American Petroleum Institute.

Code for welding pressure vessels and nuclear components by ASME.

Welding code for bridges and buildings by American Welding Society.

Considerations from customers regarding cost, reliability, and safety of welds.

The Welding Procedure Specification that outlines welding parameters and requirements.

Procedure Qualification Record documenting welding parameters and test results.

Testing must be observed by an authorized individual from an independent lab or customer.

Occurs when test samples pass, validating the WPS for production use.

If test samples fail, WPS parameters are adjusted and retested.

Once a welder passes tests, they are certified for the specific procedure.

A qualified WPS remains valid until replaced by a better process; welders also need requalification after six months without work.

The format of the WPS can vary, but it must list essential variables required by the code.

A federal or military term for WPS, which details parameters for welding.

Welding process, technique, electrode, current, voltage, and more.

The process of validating that specified variables produce a sound weld.

An initial version of WPS that needs testing before finalization.

Process of ensuring that welders can perform according to WPS guidelines.

Ranges specifying allowable amperage and voltage for welding operations.

Parameters that affect mechanical properties of the weld and require requalification if changed.

Parameters that can change without requalification of the procedure, but usually need documentation.

Supplementary information included with WPS to guide welders on setup and operation.

Joints that have established parameters and don't need additional qualifications in some codes.

Different codes have varying requirements for qualifications regarding groove weld positions.

Testing and documentation that ensure a welder can follow the WPS correctly.

Includes radiographic, ultrasonic inspection, or bend tests to verify weld integrity.

Variations in requirements across welding codes like AWS, ASME, and API for weld procedures.

A unique identifier for the Procedure Qualification Record used in welding.

The ASTM specification for the type and grade of base material used in welding.

Refers to the thickness or outside diameter of the test material being used.

Manual or automatic welding processes used to certify a welder or operator.

Classification for metals used in welding; denotes specific groupings.

Codes that define the type of welding electrodes and rods as per standards.

A classification system for electrodes under AWS standards indicating type and usability.

Groups that categorize metals based on their characteristics and welding capabilities.
