Those runners look pretty good. How did you get the shape almost perfect like that?

 

i didnt make them h23vteceg made them...but im not to happy with the cracks in the runners...

 

I am new to welding and I am almost done with my training. Right now we do SMAW (shielded metal arc welding aka stick).

We have pipes with crackes or imperfections like that when we do the root pass (first pass - joins the two pipes together full penetration).

I can't see why that crack cannot be repaired. Cut out the area where it is. Gap it to the electrode that you are using and fill it in. I know airflow is key here but you can see the crack so if you can see it you can fine grind it to keep the same level as the rest of the metal.

Again I am new at this so I am trying to figure out what the fix would be.

Could you post a picture of the outside of the pipe where the crack is?

In this picture you can see the penetration on the left side of the flange. I can't see a problem of gapping the crack. Penetration patch to weld it shut. Then grind that excess penetration to make the air flow better.

Hope this helps.

These cracks???
If you really don't like them why not weld them and then grind the welds down?

 

well i was told not to grind the inside out. i ususlly grind them out like i did with danishR. you told me not to because you had someone that was porting your head match the inside too......


the cracks are very minimal they are only little surface cracks. the tune is 1/8 thick some little surface scratch aint doing anything to it. once its sanded own and bored it wont be there anymore.

Yeah that makes sense. That is why I asked to see a picture of the pipe from the outside.

It isn't like these things are going to hold high pressure.

I start Tig in a week or so and reading these threads is getting me amped up. :D
