Limit throat thickness for fillet welds, Inspectors view?
Limit throat thickness for fillet welds, Inspectors view?
(OP)
My dear friends
At design time, we limit throat thickness to 0.707x min plate thickness, which implies that length of the leg can not be taken to be more than the plate thickness
But that is for calculations.
I am looking for a perspective from Welding Inspector's view
What is the concern if leg length happens to be somehow larger than the thickness of the plate(in other words throat thickness is larger than the above limit)
I have posted this one on AWS forum, your permission assumed granted.
Respects.

However, I have rejected items due to excessive distortion due to heat input during the deposition of oversized fillet welds.
Here are a few links with some useful information

There have been several AWS papers discussing the effect of weld penetration into the base metal. In this case, credit can be obtained for reducing the fillet weld size and not increasing it.

If you are actually welding to an edge of the plate, it is best if the weld is held down slightly from the top. Also gives a muchbetter looking weld. Otherwise, if there is no edge to the plate, such as a t-joimt, a larger weld is okay. It sometimes relives problems with a sligt amount of under cutting, which can ocurr esp. in field welds. Larger welds do need to bebuilt up in multiple passes.
