If you weld you should read this

[Zachalanche]

seen that article before, and it seems like it could be an easy mistake for a welder without formal training. Just thought I'd throw out this idea: should there be a sticky for fabrication hazards such as this. It could save one of us from making a costly mistake down the road.

It's an easy mistake for ANY welder. The guy who wrote that was a professional welder. I have formal training. I learned gas welding in Aviation Maintenance Technology at Columbus State. We didn't learn not to burn brake cleaner.

my instructor was the A&P teacher at Somerset Vo-Tech center...and he said to never clean parts to be welded except with a grinder, sand paper, or a flap wheel.....never to use any sort of solvent cause it would leave a residue that was harmful if not fatal....that was in 94'.....

i have always kept that in mind whether on the job, or doin personal stuff....

If you can, you should grind all weld surfaces first, galvanised, painted, rusty and even new steel. This is prep enough for welding of any kind - no need for brake cleaner!

Just remember to wear some kind of fume mask whilst prepping (and welding if we are going to be 100% correct)

Wow. That's nuts... Just a little puff of smoke. I know if I have to use brake clean in my garage in the winter time (door down and salamander blasting) I wait till that's the last thing I have to do and go in for the night after it's done. I've been in the garage when brake clean was used while the salamander was still going and it will take your breath away and give you a really bad headache and probably a lot worse that I don't realize.

If you use cleaners period you should read this.

Wow that is a frighting man. I do all sorts of stuff with cleaners all the time and like most I dont read. This just changed my tune for sure thanks you may have saved my life. http://www.brewracingframes.com/id75.htm

i would say it's already on an old thread, but it's just simply a repost, it's about 3 threads down.

commented last... YESTERDAY.......................

is this the one where the guy uses another cleaner and he gets a little whiff of the smoke and almost dies? i assume it is and in that case its a re-post

Phosgene gas...

How is that guy doing now?

yep used by the Germans in WWI, nasty stuff. If you are into BMX Brew makes some kick ass frames

The best weld prep is a machined surface...
followed by sanded or ground surface.

Any other form of prep(such as spraying it down with a solvent, heating it with a torch, etc) leaves residues that can prevent proper fusion, cause porosity and slag inclusion...all of witch lead to a weaker weld that may prove to be fatal if the weld is used in a critical operation.

This should be kept in the minds of all welders/fabricators...especially if they're making roll cages, suspension parts, frame mods, etc where safety is a priority(I hope.)

yeah this is a re post but people shouldent need too look for this stuff it should be presented too the public always. It's never too late for a reminder.

could be but who cares, seems to have helped even professionally trained individuals down to the novice DIY hobby welder many of whom learn by trial and error, which is not a good idea in this case.

IF its a repost FIND IT! I myself have never seen this information here on TRS before I put it here and even if it was I DGAF. I thought it was an informative article and simply posted it up here to pass the word along. I myself only clean welding surfaces with an angle grinder and a flap wheel.

Ranger1 go suck phosgene gas!!!!!

i'm a 2nd year Alberta welder. NO ONE wants to be breathing phosgene gas, that will put you down and out.
