Study Notes
Welding Symbols and Fillet Welds
- Welding symbols indicate the area of common contact between the members to be welded and are identified by arrows.
- The arrow side of the joint is the side to which the arrow points, while the opposite side is the other side of the joint.
- Fillet weld size must be shown for each weld symbol on the same side of the reference line as the weld symbol.
- When the fillet welds are on both sides of the joint, their sizes must be specified, whether the dimensions are identical or different.
- Equal leg size fillet welds are indicated when both leg sizes are equal, and the size is specified to the left of the welding symbol.
- Unequal leg size fillet welds are required to be identified on the welding symbol, with the size specified to the left of the welding symbol.
- The application of fillet weld symbols includes fillet welds in hole (or slot), double-fillet weld symbols for one and two joints.
- Intermittent fillet welds are of three types: basic intermittent fillet welds, chain intermittent fillet welds, and staggered intermittent fillet welds.
- The lengths and position of the intermittent fillet welds are placed next to the fillet weld symbol, with the pitch specified to the right of the length dimension on the symbol.
- The basic intermittent fillet weld has one line of welds, while chain intermittent fillet welds have opposite alignment of weld segments across the joint.
- Staggered intermittent fillet welds involve double-fillet welds in two lines, with the centers of weld segments on each side of the joint being offset in relation to one another.
- The application of a plug weld symbol includes specified dimensions for diameter, depth of filling, and the center-to-center spacing or pitch.
