What I did in about 2 hours of "free time" today, LOL...free time meaning not putting out any fires...
Built up a jig on the welding table to make some ladder assemblies for the grabber arms on some of our trucks...simple stuff, but I still think it's cool...nice change of pace
Side pieces set up, one side tacked, with the spacer jigs tacked in...
Quick fit check to double check dimensions are good with the cross bars
Other side rail tacked in, and cross bars tacked in every foot...
Got the rest of the cross bars (short some, waiting on 3/4" round stock to finish) in place...
Welded in what I could, both sides...will have the rest of the round stock in early next week. 3 more to build after that, should go quickly...

Hey, ladies, a question about weld-through primer. A member here told me about it, and I got some from Amazon. 3M. I see it has a high zinc content. I have been warned about the dangers of welding galvanized metal because the zinc makes a nasty toxic gas when welded.
So why is it okay to weld through a primer that is high in zinc?
And would it be okay to use a high-zinc cold galvanize paint as a weld-through primer?
Getting ready for a major rust fixing project on my Jeep. I'll be cutting up my scrapped 94 for practice pieces!

Weld thru primer is used in collision repair to replace the zinc coating imbedded in sheet metal panels only when it is ground off during the repair. It was designed to be used ONLY on bare metal mating flanges where special spot welders are used. It has very poor adhesion properties and will fail and peel if used on surfaces other than the inside flanges in a pinch weld. It's one of the most misunderstood, and misused products in the industry. Some auto manufactures do not even allow it in their repair procedures at all.
If you're going to use it for something like frame stiffeners, only spray it on the back side of the stiffener. Dont coat your entire unibody rail with it. You're also correct about it being toxic and DO NOT, use cold galv anywhere near a welder.

I'm just a rookie welder, but two things I know:
- Don't weld zinc.
- Don't weld brake fluid.
Okay, so how is it possible to weld brake fluid? Simple, use it to clean parts, then weld them. It hangs around. Any hidden little pocket can ruin your life, and possibly kill you. When subjected to the high heat of the arc, it forms phosgene, which was used in WWI as a poison gas. Nasty stuff.
I believe it's the older, more effective chlorinated brake cleaner that is dangerous, and the new stuff is supposedly safe, but I think I'll just stay away from either kind.

Definitely welding related... Also strong language, so be warned.
Im dying laughing right now.

I've heard from several how-to's and welders that it's okay to use the non-chlorinated to clean or prep for welding, most say to just use alcohol... I guess acetone is okay too?
