weld size fea

[CAD-One]

I am using inventor professional 2013.

I need help with analizing this aluminum pipe weldment. This part is clamped using 2 1/4-20 bolts thru the holes to a rigid wall. I want to know if the weld size is adequate to hold 200lbs load. How can I go about this ? Please see my questions. 

1. We don't use the frame generator. Its just a simple assembly made of extuded parts. Should it be converted to a weldment to get weld fillet size results?

2. Should it be a ipt or iam? which is better?

3. Apart from the weld size, I want see if the pipe wall thickness is adequate enough to hold 200lbs load.
