Calculating Min. Weld Thickness for Allowable Stress

[Daniel Turner]

Hi guys,

Quick question, How do you calculate the min. weld thickness needed for an allowable stress?

You calculate shear flow I assume?

Thanks in advance!

For most applications, the weld size is determined by the amount of shear it must resist; in other situations, the stress in the weld can be a combination of shear and bending.

There's no hard and fast rule. Weld design and analysis are just a couple of things an engineer does when looking at making something.

These books by Omer Blodgett have found wide use by engineers who design welded structures:

Blodgett is an excellent reference and they are not expensive books to purchase. Treating a weld as a line has saved me lots of time. :)
