Here are some examples of our Aluminum cylinder head welding. These photos show the type of aluminum cylinder head damage we repair.
First, all the broken parts are removed. We will preheat the cylinder head to 275°F in our 100 cubic foot computer-controlled electric element furnace. The Combustion chamber, valve seat registers, intake, exhaust ports and deck will be T.I.G welded. When T.I.G weld aluminum cylinder heads, we use filler rod of the same alloy as the head.
Big Block Chevy Aluminum Cylinder Head

The damage to this aluminum Big Block Chevy cylinder head was caused by a valve train failure.

This is a good example of our aluminum cylinder head welding. After T.I.G.-welding the damaged combustion chamber, we then digitize the adjacent combustion chamber. Our welded combustion chamber is identical to the original combustion chamber. The replacement valve guides installed and honed to fit. The valve seat registers were machined to their original heights. Our new valve Job sets these valves at the same height as the other valves. We removed the old spark plug and saved the spark plug threads. Notice there is no spark plug Heli-Coil. When valve guide bosses are cracked, we weld the entire boss then machine new valve guide bosses in our five-Axis C.N.C. machining center. Since being repaired, this aluminum cylinder head has over 200¼ miles passes with a 300hp Nitrous Fogger System. We have made other repairs to these heads but have had no problems with this repair. Look for the “BB2 Saga” in how we do it.
Dart Pro Stock Big Chief Cylinder Head
Vintage Ferrari Maserati Combustion Chamber

We have restored the chambers in this vintage Maserati cylinder head. The damaged chambers have been T.I.G. welded. We then digitized an adjacent chamber. Next we machine new valve seat registers. New valve guides and seat inserts will then be installed. All the Maserati chambers are machined to their original size

Ford Hemi Combustion Chamber

Here we show the 800 cubic inch Ford Hemi Pro Stock aluminum head repaired. We digitized an adjacent chamber. Then we C.N.C. machine the damaged chamber to its original size. Last, we re-machined the valve seat registers. We then installed new bronze valve guides and seat inserts. (See “How We Do It” for details.)
Supercharged Dodge Viper Aluminum Cylinder Head

The deck surface cleaned with .003 inch material removed. While welding NEAR one of the intake seats I heard a cracking sound. I alerted the local engine builder to this damage. The engine builder blamed me for causing it. I suggested it was already cracked because there was no evidence of the seat being touched with the torch. What do you think?
