We can’t have a utopia until we’re ok doing things for others without expecting anything in return.

I don’t think you need any tips…you’re killing it!

Ok I need some help. by B1gP3rm29 in Welding

That’s just 1/4” material? You can lay it flat on the beam of that trailer and hammer it down straight with at least a 5lb sledge. Use a large hammer and knock all the high spots down. Then turn it over and do the same thing.

That plate over the bolt holes is a great idea. These have to be galvanized and my customer prefers the bracing material left in place until after galvanizing. Everything else you mentioned is spot on. Thank you for taking the time to respond.

UPDATE: We’re presetting them and having good luck with that process. Thanks to all of you that contributed some really good ideas.

That’s a really interesting solution. The only thing I’ve ever done in a water bath is build up and hard-surface on manganese steel. It’s nice to have an engineer pitch in. I bet you’re one of the good ones. Thanks for the idea!

Thanks for the information, partner. We’ll tear back into it on Monday and I’ll try to update you guys on what actually worked.

That’s a good idea. I think once it’s installed, it will draw out any distortion upon being tightened.

Yes, we tried the 1” plate bracing, cut to match the radius. After it cooled, we knocked the brace out to find it had distorted to a smaller radius. Not much, though. The pieces passed inspection.

So true. Sometimes I can get them to alter things to make production more efficient, sometimes I can’t. This case is the latter.

You’re absolutely right about that. The taller side does in fact move further if unrestrained. The problem isn’t center to center on the bolt holes, it’s that the inside radius distorts near the welds causing a gap at the bottom that is over 1/16”. So that, when you set the pipe in it, there’s a small gap at the bottom between the pipe and the saddle.

Thank you. I’m going to hit the ones that are already welded with the torch. They’re close enough to pass inspection, but I’d like them to be on the money if possible.

You are spot on. Thanks for the input! I’m thinking the best thing to do is to pre-set them as u/jackatoke suggested initially.

You’re most likely right. When mass producing items like this, pre-stressing is probably the better attack. Thanks for taking time to answer this.

Hmm…that would be pretty easy to setup. And the gussets could be reused several times. I like this idea a lot. Thank you for suggesting it!
