Welded Uprights
Back in the GTV6.ORG days Barry posted some pics of a front upright (stub axle) that had been cut and shortened for an "upsidedown ball joint" mod.
Was there anything special to welding this - pre & post weld heat treatment ?
I have put an upright on a nuclear analyser and come up with a material called "Tool L7" - anyone know the welding procedure for this ?
I've been out of the forum loop for a while and this is my first post in the new site so I hope I've done this right.

Daniel,
You are correct to ask a question about this matter. I do have a question for you however:
When you had the chemistry evaluated, how many elements can the unit read? The tool steel you identified is an odd choice for such a part. If you can tell me what elements you have, and their percentages I think I can help you identify which processes you should utilize to do this process not just look good, but work well long-term.

Hi All
I think that was Julien and not Barry, but I too would like to know what the welding entails
If I may ask, why do you need to shorten the uprights? If you use a 17" wheel, I think you will be able to fit the A-arm underneath the upright if you use something like a Lada's ball joint. No welding, just a bit of drilling...

I have extended uprights meant for 16" wheels. On the track I wish I could fit 15" wheels. As far as I know Beninca reinforces the welded ones. The ones I have, 2 spindles were used per side to make 1 extended unit, and they were cut at an angle. I think TIG welded, I could be wrong, but I doubt if they MIG welded.
Sounds like what I am aiming to do - 2 uprights to create 1 but the welding procedure is critical, especially with alloy steels. Do it wrong and you end up with hydrogen embrittlement (bad things happen ), cracking etc.
Z - Why do you want 15" wheels over the 16's. Is it for tyres?
I need my 16's to fit over the brakes.

In my case, I used to have 14" magnesium rims which needed shortening of the upright.
Another problem we solved by welding is the hole for the ball joint.
It is tapered, not straight. This means drilling it is not that easy. Hence, we just took the enitre lower part from the donor car including the tapered hole.

Finally have a home internet connection - slow but it's a start.
I'm still looking for a weld procedure for tool L6 which has the composition -
Cr - 1.2%
Mn - 1.3%
Fe - 96.5%
Mo - 0.05%
C - ??% (The machine couldn't read carbon content)
Any help on this, or anyone who has welded uprights and can tell me what they did will be appreciated.
Thanks
