Unfortunately, Steel can NOT be welded to Aluminum.
The frame is shot. Maybe you can salvage the components (wheels, deraileurs (shifters) , brakes, pedals and crankset.)
You didn't say how much you weigh, but I would recommend a steel alloy frame next time , such as 4130 Chrome-Molybdenum, also-known-as "CroMo", and it should be oversized tubing.
If you want a second opinion, please include a photograph of the damage. And tell us how much you weigh.
