Final answer:
In engineering, welders' proficiency is visually reviewed against the test plates at regular intervals to ensure the quality of welds.
Step-by-step explanation:
In engineering, welders are often required to demonstrate their proficiency by welding test plates. These plates are inspected visually to ensure the quality of the welds. The frequency of reviewing a welder's proficiency against the test plate can vary depending on industry standards, regulations, and the specific project requirements.
Typically, welder's proficiency is visually reviewed every few days or after a specific number of welds. This allows supervisors and inspectors to ensure that the welder is consistently meeting the quality standards and producing sound welds.
Regular visual reviews help identify any flaws or issues with the welds early on, allowing for prompt corrective actions to be taken. It also ensures that the welder's skills are maintained and any necessary adjustments or retraining can be provided if needed.
