Weld thickness

  1. Jan 6, 2015 #1
    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. :)
