If periodic inspection of structural welding is allowed, what must be performed prior to welding?

The correct answer indicates that all types of inspections must be performed prior to welding. This approach ensures a comprehensive assessment of various aspects that can affect the integrity and quality of the weld.

Material inspections are crucial to verify that the materials being used meet the specifications for strength, ductility, and compatibility with the welding process. Safety inspections help ensure that the welding environment is safe for personnel and that proper safety protocols are followed, reducing the risk of accidents or injuries. Visual inspections allow welders and inspectors to identify any surface defects on materials or components that could lead to issues during or after the welding process.

By requiring all of these inspections, the process enhances quality control and safety, ensuring that the final weld complies with structural integrity standards and reduces the likelihood of failures in the field. This multifaceted inspection approach is vital in structural welding to maintain quality, safety, and compliance with established codes and standards.
