Effective Throat Area for Bevel Welds
Effective Throat Area for Bevel Welds
(OP)
I need to figure out the throat area for a weld on a 1.5" rod welded to a pin eye. the weld type is bevel groove.
i am using this formula but it doesn't seem right to me:
A = pi/4 * [(Do-Di)/cos(chamfer angle)]
can someone tell me if this is correct or another formula.
thanks in advance.

RE: Effective Throat Area for Bevel Welds
Et = 0.64 R for GMAW and FCAW (G), where R is the outside radius corner and the weld is filled flush
Et = 0.31 R for SMAW and FCAW (S)
Et = 0.64 R - Df where Df is the distance from the outer wall of the round to the weld face and the weld is NOT filled flush for GMAW and FCAW (G)
Et = 0.31 R - Df and the weld is not filled flush for SMAW and FCAW (S)
For flare-V groove, the constants 0.73 and 0.61 are inserted in the above equations.

In the case of a bevel weld I would likewise choose (within reason)the distance from the least penetration to the outside surface of the weld. The PE board of examiners tends to accept this approach as the real-world.
