There is a weld at the start of the trajectory, and a space at the end. In a completed weld, the junction between the surface of a weld and the base metal. 2. In other words, the three criteria the inspector should look at are: 1) The minimum size of the fillet - as specified by the welding symbol. The duration and spacing of the welds can vary widely based on the application. The term used to describe the center to center spacing of intermittent fillet welds. (38. The difference between a spot weld and a tack weld are that a tack weld is a temporary initial step to position work pieces and ensure the correct alignment for the final weld. 17. 3 Intermittent and zig-zag fillet weld symbol. 5. 3.

This satisfies the minimum length requirement without violating the max pitch requirement and also Al's penchant for standard terminology, all by simply adding 1/2" of weld. Specifications, Process, Notes, Etc. What does the 7 mean in the picture. FIGURE 10. Posted on by Leave a comment. Since this is an axial only member (theoretically) I would just divide the axial strength required from the angle by the weld strength to get a length required, and use intermittent welds to get that length. However, if the size of the fillet weld is not even, designers can use two numbers in the form of, e.
