Nice to see my old 1303

type 4 turbo as usual

Tried something fun yesterday. People always say that aluminium is soo hard to weld, but...how hard can it be? jonas Linder gave me some welding sticks and i had to try them out on a old cracked head..

the thought was to build up some aluminium on the inside of the exhaustport to be able to get the curve smooother for the exhausts.

First i started with grinding out the port to get rid of the carbon and dirt.

Then i just welded in the port:D

It was mutch easier than i had ever imagined

then i grinded the port to it´s new shape, hard to see in a picture but it really feels better;)

Ok, i know i should have preheated the heads, and there is probably more things i did wrong.. but this was just for learning:)

I tried to do a reinforcement to the head just for fun. I didn´t cleaned the head at all at this spot, just welded an d it seemed to work fine

Someday i´ll do some work on my real heads;)

Good results Jonas!

The boxing of the fins by the exhaust port in that last pic looks perfect!

Thanks! but the boxing in the last pic is made by a professional welder

But i like to do things myself, thats the fun part of the hobby! so...i cant take any credits for that welding.. but the crap in the ports are mine

Please......

Its, set to 80-100amps the rods are 2,5 or 3,2mm i tried both and they both worked fine.. Jonas Linder supplied me with the rods, I think he knows the identifying number.
