We were hoping a big team would bring an engine driven TIG welder we could use.

And this will only be the second time my team will go to World's and we are a team full of new team members (2 returning members out of 9), so we didn't realize their was a machine shop we could use. Thank you all for the help! The team was happy to hear we will be able to weld our arm back together if it gets worse.

I'm glad you found the help you needed. Congratulations on getting to champs!

Please pay attention to all of the manuals. The only place a robot can be worked on at any competition is in the pits. No work can be done outside of the venue and brought in (such as after hours in a hotel room). The machine shop (or official venue machine shop designated area) is the only place welding can ever occur.

Look for this IN the pits at Worlds.

Not sure what to say...

This would not insulate from the current that is used when welding.
As well I am not sure this would even stop any heavy slag...

Luck was certainly on your side!
:D

As I recall the NASA machine shop was setup for MIG welding, not sure if they had TIG there.
Though it has been a few years since we needed welding at the championships, thankfully.

Aloha!

Thank you all for the help. Some people at Michigan District Championships asked us about the cracking, and it is not a serious problem to any that are wondering. They are minor cracks that we wanted to prevent from spreading. We were able to use bolts to hold everything tight together.

Allister,
Venues like the Jones Dome do not allow open electrical power on the exterior of the building here in the states. Any outlets are in locked cabinets that require electricians to manage who, what and how much.
As a part of history, the I.B.E.W., The International Brotherhood of Electrical Workers, of which I am a proud member for 43 years, started in St. Louis in 1891. Some of the people you will see working the venue are members of Local #1.

Warning. Welding while you still have electronics installed can be catastrophic to them. The machine shop folks will warn you of this and in addition will not be held responsible if said electronics are damaged..

If you are able to, remove what electronics you can. We were not able to remove our electronics board due to time constraints, had to rush to the field as it was after the fix. Luckily we keep a majority of our electronics on Lexan sheets and we didn't have any damage.

Just be aware it certainly could.

Good luck at Champs!

Aloha!
Did the NASA Machine Shop staff say what sort of hazard the welding process posed? Heat? Splatter? Risk of return currents flowing through the electronics? Magnetically induced currents flowing in the electronics? Other?

Can someone who will be going to Champs ask?

Might be dated, but last time my team got a weld job from them it was more of a general waiver statement

They specified the rick of returning current flow. This was when we were still using the cRio, never the less, when a NASA machinist advises caution, it must be observed.

Hope to see you at the championships,

Aloha!
