How do I specify the spacing around an arc?

[jmarkus]

If I have a pattern of welds around a circular edge (say fillet welds) how do I define the spacing? For example I have 4 25mm welds around a 74mm diameter. Do I measure the circular arc length as the pitch and put 25-58.1 on the weld symbol? Or is there is different way to define this?

Thanks,
Jeff

The same way you would specify a stitch weld.

For a stitch weld along a line, I use the linear pitch. So are you saying around a circle the radial pitch is correct?

 

[Ron]

yes.

I guess if it's not equally divisable, then you keep going around in circles until you have a complete fillet weld <G> (I couldn't restrain myself, sorry).

I think you are measuring circumferential pitch, not radial. Also, you may use the tail of the weld symbol to clarify your intent in the finished work.

Yes, circumferential. I got my terms mixed up.

Thanks,
