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:

Safety Q&A. Ask questions, hopefully find answers. (self.Welding)

submitted 2 years ago * by ecclecticWelder/ Hydraulics (V)

Inspired by /u/brad3378

This is a little beyond the scope of our normal safety meetings, as it will aim to directly address issues that people may be having in their workplace and would like to have some direction in where to get more information or who they should contact.

Evidence, links, and other support for any top level responses will be required, OSHA, legislation, existing cases etc. are good places to start. Any links that are behind paywalls are kind of useless, but abstracts may be acceptable.

This will stay up as a sticky for a few days, a new one will go up next Sunday with a compiled list of questions and answers from the last week. If this goes well, it will become a recurring post.

Topics that have been suggested will be listed as comments in 'contest mode' feel free to answer the existing ones, or post your own.

Never weld without a proper face shield. (like they do on those chopper building shows)

Welding galvanized steel creates deadly poisonous gas. (Not deadly so much as problematic over a long period of time)

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?
