This could be a convex weld (a weld that makes a rounded outward like a 'hump'), a concave weld (a U-Shaped weld), or a flush weld in which the weld is flush with the two surfaces of the joint. This makes it easier to weld a joint without having to clamp it. In contrast, a welding symbol is the complete information package the designer wants to relay to the welder. Giving some thought to this is also part of the design process. When a full penetration weld needs to be completed where both sides are going to be welded, quite often we may have to back gouge out the root of the primary weld before we apply any kind of filler material behind the joint of the weld. One needs to understand the welding processes, know how fatigue will impact the structures life, plan out joint design, understand how welds with deform the structure and ensure manufacturability.
