I have a steel Blow of valve flange and i wanted to weld it onto a AEM cold air intake for integra, but i believe the intake piping is made of out aluminum? So the aluminum would melt when trying to weld?

 

not weldable, get an aluminum flange from TiAL, I think we can get them!(not an advertising pitch, just trying to help you out).

 

You can always have it brazed on.

 

braize aluminum to steel, wtf?

There was a large thread about this before.

That's what brazing is commonly used for: joining dissimular metals. Brazing if done properly is a rather strong weld (it's used on the fins inside torque converters).

 

You CAN braze it...but if you want something to look decent, go ahead and get the aluminum flange.

 

braze it if you can, function over form.

There's more issues to consider...especially when welding will serve both of the above.

How about the issue as to whether he even has access to a torch to braze, or if he knows how?

A good welder will be able to have a good looking braze weld. My old welding teacher could make a braze weld look like a tig weld (besides the color of the filler).

You can always take it to a machine shop or a welding shop.

I know the kind of work that comes from most welding shops. What I'm saying is that with the info he gave, we don't know so many things...

Sure, he may take it to a welding shop and have it brazed, but then the cost may be higher than if he bought the right flange and welded it himself.

Many times, you just don't have any idea what kind of work you will get from any "local welding shop."

Odds are, getting the RIGHT flange will be the best thing. There's reasons that you seldom see one brazed on.
