Fillet weld leg length

Fillet weld leg length

Fillet weld leg length

Is there any requirement for the size of fillet weld leg length in accoeding to standard or code?

RE: Fillet weld leg length

AWS D1.1 has minimum fillet weld sizes based on the thickness of material.  It also specifies that if a fillet weld size is not called out on the drawings, that the minimum fillet weld size applies.

RE: Fillet weld leg length

Thanks GRoberts.

How about the maximum leg length? i have read some post and the information from the internet talking about that , but i still can't be sure that the maximum value of that.

RE: Fillet weld leg length

For AISC and AWS codes, there is a maximum weld size in lap joints.  If the material is >= 20 mm (or 3/4"), the fillet weld must be at least 2 mm (or 1/16") smaller than the material thickness.  This is for inspection purposes--if the weld comes all the way up to the edge of the material, it can melt away the edge so that what looks like a fillet weld that is the same size as the full material thickness will actually be undersized.
