There are times when an unequal leg fillet weld is called out. If a double fillet weld is called out the size will be shown for both sides of the joint, depending on the part these welds could vary in size so it is necessary to provide this information. If it is an equal leg fillet weld it is not common to dimension it on the print as shown below for demonstration purpose. If a single size is called out this is specifying that weld should have equal leg sizes. The size is indicating the leg length of the weld. This size is called out on the left side of the symbol before the vertical side. The vertical leg of the symbol will always be placed to the left regardless of which way the arrow is pointing.įillet welds may have a size associated with them.
These welds can be applied on varying angles but this would be the most prominent.Ī fillet weld symbol can be used with an arrow side (below reference line) other side (above reference line) significance or on both sides (both sides of the reference line.) When a fillet weld is required on both sides of the reference line it is called a double fillet weld. This weld is used when the joint has two members coming together to form an intersection of commonly 90 degrees. Fillet welds are one of the most common weld types in the industry.
