Study Notes
Welding Qualification and Certification Guidelines
- Welder’s qualification is valid for two years, unless there are specific reasons to question ability or a shorter period is specified in the qualification.
- If a welder’s ability is questioned, their qualification is suspended, and they must pass a check test before reinstatement.
- A welder’s qualification may be revoked if not engaged in welding for a specified period or leaves the employ of the company.
- Welding operator’s qualification remains in effect indefinitely unless there is a specific reason to question ability or a shorter period is specified in the qualification.
- Similar to welders, a welding operator’s qualification may be suspended or revoked under specific conditions.
- A welding operator qualified with a single electrode process is deemed qualified for welding with multiple electrodes for the same process and vice versa.
- A robotic welding programmer’s qualification may be issued by the CWB under certain conditions and may be revoked if not engaged in robotic programming for a specified period.
- The qualification issued by the CWB for robotic welding programmer performing tests on a specific assembly is transferable and remains in effect for two years unless there is a specific reason to question ability.
- A robotic welding operator’s qualification remains in effect for a specified period, unless there is a specific reason to question ability to operate the robot.
- The qualification issued by the CWB for a robotic welding operator performing tests on a specific assembly is transferable and remains in effect for two years.
- The qualification issued by the CWB for a robotic welding operator performing tests on an alternate assembly is non-transferable and remains in effect indefinitely.
- The guidelines also specify the renewal process for qualifications.
Welding Qualification and Testing Procedures Summary
- Welders qualified with a certified electrode and shielding medium combination can weld with any other certified combination for the same process.
- FCAW process qualification with self-shielded electrode also qualifies for all flux-cored and metal-cored gas-shielded electrodes.
- Separate qualification is required for welding on galvanized surfaces, following specific provisions.
- Visual inspection for leg size, undercut, and profile is necessary before welding the groove on a fillet weld using Option 1 of Figures 8 and 9.
- Welds subject to radiographic testing must have no cracks and meet acceptance criteria detailed in Table 21.
- Radiographic examination may be used at the company's discretion for all processes except for semiautomatic GMAW, which only allows bend tests.
- Root-bend tests may be conducted if radiographic examination indicates lack of fusion, with results taking precedence.
- Radiographic examination is limited to specific sections of the plate assembly for different welding processes.
- The reinforcement for radiographic examination must be flat and smooth, and the backing need not be removed.
- The permitted imaging system, procedure, and technique for radiography should be in accordance with CSA W59.
- Personnel conducting radiography on welder and welding operator qualification test assemblies must be qualified as per regulatory requirements.
- Bend tests for weld specimens should be performed in accordance with specific procedures, with root-bend tests taking precedence over face-bend tests.
