What is unequal leg length in welding?
The size of an unequal leg fillet weld is the shorter leg length of the largest right triangle which can be inscribed within the fillet weld cross section. 1When the intersecting member is less than 60 degrees, the weld shall be considered a partial penetration groove weld.
What is the leg length of a fillet weld?
The leg length refers to distance from the root to toe and should be measured in both directions. The leg size is the length of the legs of an imaginary triangle that can be inscribed within the actual weld as shown with feature L1 and L2 in the image below for both a convex and concave fillet weld.
How is leg length of fillet weld calculated?
To calculate the leg size from a given throat size: Leg = √2 x Throat. To calculate the throat size from a given leg size: Throat = Leg / √2. For approximate size use 1.41 for √2 .
What is the relationship between design throat thickness & leg length of a fillet weld?
When deciding on the size of a fillet weld it should be remembered that a small increase in throat thickness will result in a large increase in deposited weld metal as the cross sectional area of a fillet weld is a function of the square of the leg length (area = z2/2).
What does the term unequal leg lengths mean?
Specialty. Rheumatology. Unequal leg length (also termed leg length inequality, LLI or leg length discrepancy, LLD) is where the legs are either different lengths or appear to be different lengths because of misalignment.
How do you measure leg length?
HOW TO MEASURE YOUR INSIDE LEG LENGTH
- Stand up straight with your legs slightly open.
- Place the top of the tape measure on your inner thigh, stay the closest to the crotch as possible.
- Pull the tape measure tight and run it down to the bottom of your ankle (just below the ankle bone that sticks out)
What is weld leg?
Leg– The distance from the joint root to the toe of the weld. Face– The exposed surface of a weld on the side from which welding was done. Actual Throat – The shortest distance between the weld root and the face of a fillet weld. Reinforcement– Weld metal in excess of the quantity required to fill a joint.
How is fillet size measured in welding?
The size of fillet weld height approximately specifies the = 0.7 formula, where z is the fillet weld width. Minimum fillet weld height is selected according to the thickness of the thicker welded part and according to the material.
When the size of weld is 10 mm What is the value of throat thickness?
What is the effective throat thickness dimension of 10mm fillet weld made by shielded metal arc welding and submerged arc welding? effective throat thickness = 0.7a = 0.7×12.4 = 8.6mm. 6.
What is the size of an unequal leg fillet weld?
For unequal leg fillet welds, the “size” of the weld is the leg length of the largest right triangle which can be inscribed within the fillet weld cross section. . X min. = 1.4 T1 or thickness of the Hub, whichever is smaller, but not less than 1/8 in..
How do you determine fillet weld sizes?
1. Fillet weld legs determine fillet weld sizes. Fillet weld sizes are measured by the length of the legs of the largest right triangle that may be inscribed within the fillet weld cross section. Fillet weld sizes determine theoretical throat.
What is the leg length of a weld?
The leg length is usually designated as the size of the weld. The throat of the weld is the distance from the center of the face to the root of the weld. Explore more on it.
How to develop the strength of a plate using fillet welds?
To develop the full strength of a plate using fillet welds, it is necessary that the leg size of the fillet be 3/4 of the plate thickness.
