The only thing that might work is to have a long enough sleeve that will connect the two parts.

However, the short length one side and the fragility of the remaining portions will probably mean it will fail in short order.

The best options in order are (imho) :

1. new part - you don't want to spend money...

2. a second hand part - visit a breakers, but inspect for condition

3. a sleeve (likely to fail rapidly)

And, even if you did have a welder, you would need something to weld to... Last time I tried to weld something that bad, the metal ran away from the torch... :)
