Leg length of fillet weld
The fillet weld leg length is the length of the legs of a triangle that bounds the cross-section of a fillet weld. It defines the geometric extent onto the adjacent part surfaces.
Physical-Chemical Mechanism of Action
The fillet weld leg length describes the length of the legs of a right triangle that bounds the cross-section of a fillet weld. It indicates how far the fillet weld penetrates into the adjacent parts and the size of the cross-section.
Metallurgical Relevance & Risks in Welding
A leg length that is too large can lead to uneven stress distribution, causing cracks or distortion in the part. A leg length that is too small can result in poor contact and insufficient weld quality.
Workshop Practice & Instructions
When welding, it is important to measure and control the leg length precisely. A leg length of 2 to 3 mm is generally suitable for most applications. For special materials or under high stress, a custom leg length may be required.
