Safety meetings occur on the first Saturday of each month
Please review the OSHA regulations for your area if you are a professional welder.
See the Wiki for more safety information

Also, please review our Safety Q&A

THIS IS NOT AN ENGINEERING RESOURCE!

While we're more than willing to assist with a plethora of questions and problems, if you're building anything that would otherwise require an engineer's stamp on it, don't take a chance. Just as /r/health isn't an alternative to a doctor, we are not an alternative to an engineer, any ideas here MUST be run through proper channels. Any dangerous or questionable advice will be summarily removed.

Modifications to vehicles beyond bodywork:

Anything to do with the frame of a vehicle, roll cages or any integral safety component on a car should be done by a qualified welder/mechanic unless you have a VERY good insurance policy. See the above section, if you don't know, take it to someone and find out. As much as we are able to help, we are anonymous strangers who you have no recourse against if something goes wrong. A highway or raceway is not the place to test your garage hero welding skills. (this notice is subject to change)


PLEASE NOTE:


There is a subreddit for welding employment:

I've heard about voltage reducing devices (VRDs) that reduce the open circuit voltage to 10 volts or less, which is low enough to prevent the current from going through your body. Apparently you can still strike an arc with these devices.

What are the downsides, if any? Anyone have any experience with them? If they're as good as they seem, why haven't we seen this become standard in welding machines?
