When determining the other side of a weld symbol on a cruciform joint, is it permissible to go through the solid member?

In the context of welding symbols and specifically cruciform joints, the solid member is the part of the joint that is typically not intended to be penetrated by the weld. When determining the other side of a weld symbol, it is important to maintain the integrity of the solid member.

Going through the solid member could lead to various issues such as compromising structural integrity, affecting the strength of the weld, or creating defects that are difficult to inspect and repair. The accepted practice is to weld along the joint without penetrating the base material of the solid member.

This approach ensures that the weld beads on either side of the joint are adequately placed to provide the necessary strength and load-bearing capacity required of the joint. Therefore, it is not permissible to go through the solid member when determining the other side of a weld symbol, emphasizing the importance of maintaining the physical properties and design intent of the joint.
