What is the specified welding process for scenarios where none is mentioned under the code?

The specified welding process in scenarios where none is mentioned under the code is Shielded Metal Arc Welding (SMAW). This is because SMAW is a widely recognized and accepted welding method that is versatile and can be used in various applications, making it a default choice in the absence of specific instructions.

SMAW, also known as stick welding, is favored for its simplicity, effectiveness, and ability to work well on different types of materials and in various environmental conditions, which are essential considerations in structural steel welding.

In contexts where the code does not specify a process, defaulting to SMAW ensures that there is a reliable and established method in place that complies with safety and quality standards. Thus, when considering the various options, SMAW stands out as the process that can generally be applied unless otherwise indicated, reflecting its foundational role in welding practices.
