What is the goal of joint design according to AWS D1.1?

The goal of joint design according to AWS D1.1 is to minimize the likelihood of defects. Effective joint design is essential in achieving strong and reliable welds, which is fundamental for structural integrity in welded assemblies. By addressing factors such as the type of joint, the fit-up, and the welding process, designers can create joints that reduce stress concentration, distortion, and the potential for defects such as cracks or inadequate fusion.

Good joint design optimally supports the welding process and the materials involved, ensuring that loads are evenly distributed and that the weld's mechanical properties are preserved. This proactive approach fosters better quality welds and enhances overall performance, which is central to the AWS D1.1 standards. In contrast, other goals mentioned in the choices, such as making welds difficult or increasing stress concentration, would counteract the principles of effective welding and structural reliability.
