What are the components of a job-built boiler that a Boilermaker will assemble together?

A job-built boiler is a complex assembly that requires skill in various components. The correct answer emphasizes the Boilermaker's role in constructing and assembling critical elements of the boiler. This includes setting structural steel sides, which provide the framework for the boiler; assembling piping, crucial for circulating water and steam; welding water tubes, where water is turned into steam; and setting pumps that facilitate the movement of water within the system.

Understanding these components is essential for a Boilermaker, as they directly relate to the functionality and efficiency of the boiler. Each part plays a vital role in ensuring that the boiler operates safely and effectively, which is a primary concern in boiler construction and maintenance.

Other choices mention components that are not directly associated with the core functions of a job-built boiler as constructed by a Boilermaker. For instance, while frames and walls are important in the construction of buildings, they don't encapsulate the specific assembly work a Boilermaker would perform on a boiler. Electrical circuits and motors, while they may be essential for the overall operation of some larger boiler systems, are not typically the focus of a Boilermaker's assembly duties. Lastly, insulation and foundation refer more to the placement and energy efficiency aspects rather than the
