What does API 1104 primarily address?

API 1104 specifically addresses the standards and procedures for welding pipelines and related facilities. It presents guidelines to ensure that the welding practices used in the construction and maintenance of pipelines are safe, efficient, and reliable. This standard is crucial for maintaining the integrity of pipelines, which transport oil and gas products, as well as ensuring compliance with regulatory requirements.

The focus is on the quality of welds, welder qualifications, welding equipment, and inspection processes that are essential in pipeline construction and maintenance. By following API 1104, organizations can mitigate risks associated with welding, such as failures due to improper techniques or poor-quality welds, thus safeguarding both human life and the environment.

In contrast, the other options refer to different contexts of welding that are not the focus of the API 1104 standard. Welding of buildings and infrastructure, general manufacturing welding processes, and automotive welding techniques have distinct requirements and standards that are not covered by API 1104.
