welding on cast 356 cylinder heads, I want to build up material inside ports and chambers... Does anyone have any tips on this practice? all I know so far is preheat to 300F, clean welding area lots... push the puddle rather than pull it...

The actual technique of building up material is where I could use some advice, i've never done this before.

 

Push alot of rod into the puddle.

 

That's what I was thinking but I'm glad you said that actually, I have no idea where to begin with this kind of stuff.

 

Try to build it up sytematically so its somewhat even as well....but yeah, pretty much just lots of filler rod

 

Yeah what they said. Have fun with the oil seeping out

God I hate cast AL cars parts.

Bake the **** out of it and grind it and you should be alright.

 

any tips on what kind of filler rod I should use... 4043 but what thickness?

anyone have suggestions for a good torch for getting inside ports? just something to get to the divider...

 

3/32 or 1/8" filler.
