Study Notes
CSA W47.1:19 Standard Overview
- The Standard outlines qualification requirements for tack welders, welders, and welding operators for fusion welding of steel.
- It aims to verify an individual’s basic welding skills and continuing ability in steel fusion welding.
- Recognition of personnel qualified under other jurisdictions is included in the Standard.
- Annex K specifies provisions for the qualification of welding procedures and personnel for stainless steel welding.
- The Standard does not address safety issues associated with welding and welding practices, as these are covered by CSA W117.2 and workplace health and safety legislation.
- "Shall" is used to express a requirement, "should" for recommendation, and "may" for an option within the limits of the Standard.
- Values in SI units are the units of record for the Standard, while values in parentheses are for information and comparison only.
- The Standard refers to various publications, including those from CSA Group, Canadian Highway Bridge Design Code, and ASTM International.
- It also includes references to AWS and ISO/IEC publications for welding and testing standards.
- The Standard provides definitions for terms such as "accredited testing organization," "advisory committee," "arc spot welder," "automatic welding," and "class."
- An accredited testing organization is defined as one accredited by the Standards Council of Canada for mechanical testing in accordance with ISO/IEC 17025.
- The Standard defines "class" as a category of welder qualification based on welding positions such as flat, horizontal, vertical, or overhead.
Welding Personnel Classifications and Definitions
- "T" classification refers to the ability to weld from one side without backing and achieve complete penetration in the root pass, e.g., hollow section, pipe, and plate.
- "S" classification refers to the ability to weld plates and sections for the full thickness of material, with or without back gouging, and includes qualification to weld PJP, plug, and slot welds.
- "FW" classification refers to the ability to deposit fillet welds and tack welds.
- "WT" classification refers to the ability to deposit tack welds.
- CWB is the Canadian Welding Bureau, a Division of CWB Group, providing industry services.
- Essential variables are welding parameters and data that, when changed beyond specified limits, require requalification of welding procedures.
- Group designation is the numerical system used to identify the shielded metal arc welding (SMAW) electrode classification.
- Machine welding is a non-standard term for mechanized welding, while manual welding is performed and controlled by hand.
- Position refers to the orientation of pipe and plate test assemblies and the direction in which weld metal is deposited in a joint.
- Prequalified joint is a joint specified in a governing code or standard that does not require validation of welding parameters through a procedure qualification test.
- Robotic welding involves equipment that moves along a controlled path with no manual intervention once the cycle is initiated.
- Semiautomatic welding is arc welding with equipment that controls only the filler metal feed, with manual control over the advance of welding.
