How to join steel to aluminum?

So I am attempting to build an XR tuber and have run into a hiccup. I was originally gonna try brazing the steel tube top to the stock aluminum side plates. I came to realize that I've never seen this done. Google has turned up vague answers.

My question is "is it possible to braze aliumi um to steel?"

My other options would be to JB Weld the two sections together, or weld tabs to the steel section so that I can bolt it to the aluminum side plates.

I need input please. Someone please help.

Thanks

a mechanical joint ( bolts, ect..) is the only real good answer.

The thing about that is it will limit mynlino mounting options, and cross braces will probably be needed to support the side plates. I figured JB Weld might be strong enough but I'm not positive.

Bolting it is probably the best choice.

jb weld has its places but I doubt this is one of them

JB weld when used on a single plane and with only a single planes worth of forces being applied...ie, filling in a hole....can be pretty strong. But it's multi plane strength is questionable. I've busted lockers filled with JB weld and unless you do some sort of rough sanding to metal rod, it'll just pull right out. Give it a try if you think it'll work for you, but your best bet is to make tabs or use solid rod and drill/tap it.

the only way ive seen any way to fuse to different alloys (steel & aluminum) is blast welding.

they put two different plates on top of one other,
cover them with a lot of explosive & a BIG BOOM.

fuses the two together.

Looks like Scorpion King is going to need an M80 then:ror:

Ive seen it done with a few different alloys other than blast welding, but its more like a spot weld. It also involves some really expensive machines. Good luck.

I guess i fell asleep on this thread since idecided to get pplatees cut.

I'll pass on blast welding though. I appreciate my dashing good looks a bit too much:ror:
