What is a mandatory step required prior to beginning welding according to AWS D1.1?

Confirming welder qualifications are up to date is critical before beginning any welding activities, as stipulated by AWS D1.1. This step ensures that the welders possess the necessary skills, knowledge, and certifications required for the specific type of welding being performed. It is essential to verify that they are qualified according to the pre-defined standards, which helps maintain the integrity and safety of the welding work being undertaken.

This quality assurance process is fundamental in assuring compliance with the structural welding code, which aims to produce sound and durable welds in structural steelwork. By confirming the qualifications, the project supports appropriate workmanship and adherence to safety protocols, which are essential for long-term performance and reliability of the welded structures.

Other options refer to processes that may be important for project management or regulatory compliance but are not directly mandated by the AWS D1.1 code before starting welding activities. While cost analysis, obtaining building permits, and scheduling inspections are valuable for overall project execution and regulatory adherence, they do not specifically focus on the readiness of the welder to execute the welding task at hand.
