(OP)
What is the minimum weld size allowed when using 1/16 metal cored wire?  

RE: minimum weld size

Don't understand your application. Plug weld over tube with 1/16" wall thickness? Maybe you want to post this on "Welding, Bonding & Fasterner Engineering" forum.

RE: minimum weld size

mineweld, your question is too vague.

when calculating weld size, it depends on stick/parent material used, throat size and expected loading.

Last time i designed a weld i used "design of weldments handbook" to give me an allowable stress per mm/2. Then manipulated as required to determine leg length.

RE: minimum weld size

We use 5/64" metalcore for flat welds. I had about 10 years or so welding experiance in one of my past lives.
My hip-shot response would be "as small as the welding operator can make it and still maintain proper profile, penetration and not have excessive porosity".

Beyond that, when we get into a tricky situation, we run some test welds, bend them and send out for x-rays.

Did you try the welding forum of Engineers Tips?
