What does AWS D1.1 suggest about the materials used in welding?

According to AWS D1.1, the use of materials in welding is critical to ensuring the structural integrity and safety of welded components. The code emphasizes that materials must meet specific standards established by recognized agencies. This includes guidelines for the type of steel used, chemical composition, mechanical properties, and other relevant specifications that dictate the performance of the welds and the overall structure.

By adhering to these specific standards, engineers and fabricators can ensure that the materials will perform as expected under stress and environmental conditions, thus reducing the risk of weld failures or structural collapse. This approach not only promotes quality assurance but also aligns with industry practices that prioritize safety, performance, and longevity of welded structures.

In contrast, using any materials without such specifications, selecting only low-cost options without considering quality, or choosing materials randomly would likely lead to inadequate performance and increase the potential for failure in the final structure.
