Aluminum is difficult to weld. Look at someone's aluminum bicycle. If it is a good job you will see what I am saying.
There will be a deposit of metal from the brazing rod.
SUGGESTION-you may recall seeing in every hardware store a display piece showing, selling, a product called PC7.
It is still available but no longer advertised. You need to get the broken part clean. You might want to drill a hole and put a pin into the spot you want to join. An aluminum nail would make a good pin. You want to rough everything up. You want to hold it still for ??? 8-10 hours.
Testimonial-the motor mount on my table saw with a 3/4 hp motor was glued together with PC7 about 40 years ago.
My REAL cast iron 100 year old park bench was fixed by me about 20 years ago.
Secrets-get it clean-mix the product well-do not allow it to move while curing.
