Bolt edge distance

[sdz]

For minimum edge distance of a bolt what does a laser cut edge count as?

I'd tend to think of it as equivalent to machine flame cutting. But have no technical basis for this, apart from the roughness of the resulting cut is probably fairly similar?

@ OP,

I concur with Agent666.

On another note, I would say that more edge distance is almost always better as fabricators seem to rarely get it perfectly right and bolt holes often end up getting butchered on site due to mis-fit; sometimes the engineer is never even told about such butchering taking place. But then again I presume you wouldn't be posting if you had plenty of space...

Hi sdz,

I'd classify that as a machine flame-cut edge, flame essentially referring to the heat involved with the edge preparation, and there is significant heat involved with laser-cutting. This ought to typically result in edge distance of 1.50 df as per relevant table in AS 4100 Section 9.

Thank you all, that's what I thought too.
