Fillet Weld Size Based on Loading

[dmillsap]

Hello,

I am currently designing an assembly fixture. It is 2 4.5"x36" 60601 tubes welded to a sheet of 3/8" steel.

I am looking for a reference online that will allow me to size the bead based on loading(~600lbf shear).


Does anyone have such a reference?

Thanks,

Dave

Havwe you checked Blodgett?

For E70 electrodes, I commonly use 900# per foot per 1/16" of weld.

Hi dmillisap

try this site:-

msquared,

Do you mean 900# per inch?

0.707 X (.3 X 70,000) X .0625 = 928 lb / in

Say 900 lb / in

Since you are in the US, use AWS D1.1 (Structural Welding Code-Steel)...not online,though.

Wouldn't the shear strength of the weld be determine by the cross sectional area times the tensile strength of the electrode?

Pretty sure that's one we used to do back in Blighty ABritTurner.

At the risk of making myself sound stupid, what is 60601 tube? Is that an aluminum (6061) tube? Are you welding aluminum to steel?

Engineering is not the science behind building. It is the science behind not building.
