AWS Welding Coordination & QA Endorsement key terms

A person assigned by the manufacturer to organize and supervise welding production, ensuring that welding is carried out according to the relevant quality requirements and documented procedures.

The individual within a manufacturer's organization who holds the authority and competence to direct welding coordination activities and answer for their technical correctness.

The set of activities needed to ensure welding quality, including reviewing requirements, planning production, controlling equipment and consumables, and supervising inspection and testing.

The body of welding theory and practice a coordinator must command, covering processes, materials, design, inspection, and safety relevant to the products being welded.

A written document that gives the required variables for a specific welding operation and serves as the instruction to the welder for producing a sound joint.

A record of the actual welding variables used and the test results obtained when qualifying a welding procedure, demonstrating that the proposed specification produces acceptable joints.

Welding parameters, such as material group, thickness range, process, and position, that must remain within qualified limits because changing them can alter joint properties.

The process of testing and certifying that an individual welder can produce joints meeting specified acceptance criteria within a defined range of conditions.

A practical test in which a welder makes a joint under defined conditions, which is then inspected or mechanically tested to verify the welder's skill.

The set of conditions, including material, thickness, position, and process, within which a qualified procedure or welder is considered valid without requalification.

A sample weldment produced for qualification or verification purposes from which specimens are cut and tested to assess mechanical properties or workmanship.

The controlled cutting, machining, and finishing of test samples from a weldment so that they meet the required dimensions and surface condition for testing.

Destructive examination such as tensile, bend, impact, or hardness testing used to verify that a welded joint meets specified strength and toughness requirements.

Inspection methods such as visual, radiographic, ultrasonic, magnetic particle, or penetrant testing that reveal discontinuities without damaging the welded component.

Examination of a weld and surrounding area by eye, sometimes aided by instruments, to detect surface discontinuities, profile problems, and dimensional deviations.

The defined limits and conditions stated in a code or specification that determine whether a weld or inspection result is acceptable or must be rejected.

An interruption in the normal structure of a weld, such as porosity, slag, lack of fusion, or a crack, which may or may not constitute a defect depending on acceptance criteria.

A discontinuity or flaw that exceeds acceptance criteria and therefore makes the weld unsuitable for its intended service according to the applicable standard.

Filler material such as an electrode, wire, or flux used during welding, whose storage, handling, and condition directly affect weld quality.

Controlled keeping of electrodes and filler materials under specified temperature and humidity conditions to prevent moisture pickup and contamination before use.

Periodic verification and adjustment of welding machines and instruments against reference standards so that output parameters remain accurate and traceable.

A device used to check welding parameters or product dimensions, which must be suitable for the task and maintained within valid calibration status.

A document that specifies the procedures, resources, and sequence of activities applied to a particular product to meet stated quality requirements.

The planned examination and measurement activities carried out before, during, and after welding to confirm that the product meets specified requirements.

Operational techniques and activities used to fulfill requirements for quality, including monitoring processes and correcting deviations as they occur.

The planned and systematic activities implemented within a quality system to provide confidence that a product will satisfy given quality requirements.

The organizational structure, responsibilities, procedures, and resources established to direct and control an organization with regard to quality.

The process of ensuring that only current, approved versions of procedures and records are available at points of use and that obsolete documents are withdrawn.

The ability to trace the history, application, or location of materials, consumables, and welds through recorded identification from receipt to final product.

A document supplied with base material or consumables that states their chemical composition and mechanical properties and confirms conformity to a specification.

Documents retained to demonstrate that welding was performed as specified, including procedure records, welder certificates, inspection reports, and repair records.

The amount of thermal energy introduced per unit length of weld, calculated from current, voltage, and travel speed, which influences cooling rate and joint properties.

Application of heat to the base material before welding to slow cooling, reduce the risk of cracking, and help remove moisture from the joint area.

The temperature of the weld and adjacent base material measured between passes, which must be kept within specified limits to control properties.

A person who directs welders and welding operations on the shop floor, ensuring that qualified procedures and personnel are used as planned.

The coordination activity of assessing and monitoring external organizations that perform welding or related work to ensure they meet the same quality requirements.

Evaluation of the competence and continued suitability of welders and operators, including review of their valid qualification certificates and work performance.

A situation in which a product, process, or document does not meet a specified requirement, requiring identification, segregation, and disposition.

Action taken to eliminate the cause of a detected non-conformity so that it does not recur, often requiring investigation and adjustment of procedures or training.
