Wow, I never said that. So you had to edit my words to make your point.  Interesting.




















Did you really just bring up certified welders?  :rolls eyes:  I don't think anyone who has ever brought that up realizes that you are only certified to weld one thickness of one type of metal per certification.  /rant.  Know what you're talking about if you're going to put up a lame attempt to start an argument and be condescending.

Re: More Cage Advice

Mackwa - nope, not certified - I'm the guy that gets asked to cut the welds apart at my local CC - and usually say F-NO unless you-all bring the new saw-blade (that heat-stress riser AND the type of rod used can kill a blade in seconds)!

And as to strength-of-weld and quality as seen from photos, yeah, what Mackwa said.

And-and, if you had a welder big enough to do single-pass on bridges, MAN that would trump all of you guys' welders combined and multiplied like welding bunnies!

(structural certified = three materials, same thickness, Stick weld, classes start out with single-pass and develop into multi-pass needed to pass cert... Mig and Tig are different and riders on basic structural, or can be separate and specific. Tube is yet another cert. Chro-Mo and tube is yet another... and so on...)

Also stacking weld on top of weld on top of weld does not make it stronger.

That is exactly how you weld a thick piece of metal.  You groove each piece and lay a root bead and a face bead.  Or back bead and weld reinforcement as this image calls them:

It's a little more than just "stacking weld on top of weld" but it's also structurally sound and industry standard practice.

I know this.  smile  We aren't talking about a 1/2" plate here that requires beveled edges and mutiple passes.  If you can't get proper penetration on 1/8" plate in a single pass, then 3 more passes won't help.
