Which processes are considered pre-qualified under the D1.1 code?

The pre-qualified processes under the D1.1 code are established to simplify the qualification of welding procedures and to ensure consistency in welding practices without the need for extensive testing. Shielded Metal Arc Welding (SMAW), Flux-Cored Arc Welding (FCAW), and Submerged Arc Welding (SAW) are all included in the list of pre-qualified processes.

SMAW is a widely used process known for its versatility and effectiveness across various applications, especially in field conditions where portability is essential. FCAW utilizes a continuously fed tubular electrode with a flux core, making it suitable for thicker materials and providing the benefit of being able to weld in various positions. Submerged Arc Welding, characterized by its high deposition rate and strong, clean welds, is often used in manufacturing environments.

These processes have been vetted under specific conditions in the code to allow for their use without the requirement for additional qualifications, provided that the welding is done in accordance with the parameters outlined in the code. This means that welders and organizations can use these processes with confidence that they conform to the standards set forth in D1.1, facilitating compliance and efficiency in welding operations.
