what tig rod are you using for stock intake manifolds and block/tranny pieces?

or what kind of aluminum are these pieces?

 

I use 5356 for intake manifolds. It's good for cast aluminum.

 

I've used some 4043 on a honda trans casing. Seemed to work alright. Cast welds dirty no matter what rod you use...if you get cracking with a 5356 try a 4043 rod.

 

anyone else...trying to get the right rod the first time. lol...

 

There is NO right rod for cast JAP ****.They put titanium dust in with the alum..It makes to tough and also so you don't weld on it .You buy a new one.There is nothing you can do about the bubbles.What I have found to work the best for me is to try and keep the piece as cool as you can.The hotter it gets the more it bubbles.And just keep shoving the rod in.

 

haha, damn, i feel better. I thought it was just me. Welding AN fittings on honda waternecks sucks!! lol

That **** sucks.Even the motorcycle and jet ski cases are made with that crap.

 

lol, when you coming down here to school me on my welder?

 

There's usually a ton (relatively speaking) of magnesium in AL castings from Japan. Such a heavily alloyed metal is a bitch. I don't even bother, partly because I know its tough, partly because I suck anyway. German Aluminum for some reason seems to weld ok though.

 

Yeah it pretty much sucks to weld that crap.

I kind of prefer to use 5356 for some reason that isn't really clear to me but I just use it because I want to

Most horrible thing i've ever welded was putting an IAT sensor fitting cut off of a z6 manifold onto the back of a d16y8 intake manifold. Cast to cast for the goddamn lose.

Thank god for dremels and sanding attachments

 

so what kind of base Al are these parts then?

 

anyone else?

any tips for welding this stuff?

Hope and pray

That you get lucky.


Seriously.

 

If this **** is so hard to weld becouse of the alloy, why dont attac this from a different view.

Cut out fine strings/welding material from a similar engine/tranny/whatever and try to weld using this material. Now both the materials has the same alloy and maybe it will weld up better.

Just a thought

I doubt that will work any better.

 

Why ?

Atleast you are not welding two different materials together.

 

Yea but you're welding with two shitty alloys vs welding with one good one.

 

and itd definitely be a pita to cut strips out of an old casing, lol.

 

So these "bubles" appear just by heating up the alloy with a TIG torch ?

It would be fine if someone tryed melting two similar "shitty" alloys together with a TIG torch, since the teoretical arguments why this don`t work are kinda weak.

 

It doesnt matter that they are similer it matters that they are shitty.

If you can prove us wrong and show us a better way to do it then by all means do so.

Ive had an easier time on the jap stuff than some vr6 parts i did. who knows though they might have been made in mexico lol

 

I just spent about 2 hours looking at every welding die cast page on the Internet.And did not learn anything that i didn't know. In conclusion NO there is no right way to weld die cast. Its designed to have those bubbles for light weight and strength.

hahahha, maybe, good thinking. I've only ever welded little things on BMW and Merc heads. Maybe the VW/Audi/Porsche stuff is different? I think this is why the guys who are really good at welding heads charge the rates they do...

Its not on heads that you have the problem.Its only on die cast parts.Like valve covers and brackets and ****
