# SHS to top plate weld - Calculation Throat

## SHS to top plate weld - Calculation Throat

(OP)
Hi guys,

In this situation, where we have a plate being welded along the radius of an SHS, which dimension would you use as calculation throat, to assess the weld strength?

Would you consider a1? a2? or something different?

Thank you.

### RE: SHS to top plate weld - Calculation Throat

if SHS is cold formed then No welding allowed at the corners (according to german codes)
reason is ...material hardening due to cold bend

mgt89,
I dont know where in the world you are or what code you are using but from the AWS D1.1, 2010:
Table 2.1, Effective Size of Flare Groove Welds Filled Flush
Flare bevel groove welds made using SAW, SMAW or FCAW-S, Teff = 5/16 x radius*
Flare bevel groove welds made using GMAW, FCAW-G, Teff = 5/8 x radius*
