Welding Qualification and Certification Guidelines Quiz

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.
