Cylinder to Tangent surface Weld Help
(OP)
I am having trouble with the weld bead options in Solidworks. I need to test a hook and have to include the welds on the metal rod. This weld is somewhat unique because it is between one end of the rod curled around and welded further down to the side of the same rod. I have tried following the basic weld procedures in Solidworks but am faced with various errors each time. Any help would be appreciated.

It seems you are trying to setup an FEA. You will likely have to model the weld bead into your part and include any voids at the root of the weld. You will also have to figure out what the residual stresses remain from the welding process and differences in material properties in the HAZ.
I would strongly suggest that you also make an FEA model of every one of the hooks that have broken using actual geometry as it was in the broken part to establish a knockdown factor for the weld strength. And of course you need the loads when the hook broke.
I would also strongly suggest that you have a metallurgist look at any failed hooks to determine what the cause of failure was. It could be a manufacturing problem, fatigue or strength. Until you know that you are shooting in the dark.
You might get more specifics on the Cosmos/Simulation forum.
