All of the following procedures are required EXCEPT?

The correct answer highlights that while several procedures are essential in the context of container repair and maintenance, the use of radiographic or magnetic particle non-destructive testing (NDT) equipment for welds is not universally required.

In the context of container repairs, ensuring that welds are free from defects is important, but the methods used for inspection can vary based on industry standards, the specific regulatory framework in place, and the practices of the repair facility. While radiographic and magnetic particle testing are highly effective methods of inspecting weld integrity, they may not always be mandated for every repair scenario. Other inspection methods, which could include visual inspection or less intensive forms of testing, might be deemed sufficient, depending on the repair context and regulations.

In contrast, the other procedures outlined are critical for effective and safe repairs. Removing weld smoke and spatter ensures proper adhesion of any paint applied afterward, which is vital for protection against corrosion. Restoring damaged components to their original size and profile is key for maintaining the structural integrity of the container. Additionally, painting replacement steel components with a compatible coating ensures uniformity and longevity in protection against environmental factors. These procedures contribute directly to the safety, durability, and compliance of the repaired container.
