What weld is called for?
What about the radius of tube or is it an arch tube?

So many questions.
Good Luck

I presume when you say "in a T configuration" that there will be two fillet welds and two butt welds. At least if you are welding all the way around.

My first impulse is to say GMAW but that is hard to say without knowing more about the job, any applicable code, and your shop setup and available equipment.

Thanks for the comments and quick feedback. Yes, it is matched wall tube so two fillets and two flare groove butts would be a correct description. The GM's idea was to implement some sort of press jig to implement ERW at the tee weld. I have 0 experience with ERW. But first thought is that it is not compatible with tee joints.

I have as much information as you do at this point. I would assume it's commercial work, no code. Also, any ERW/GTAW equipment would need to be purchased.

This is baby steel when we work daily with jumbo i-beams and girders. I'm pretty sure they just want to know which way to go for the estimate.

Thanks for the help!

Sub it out to a job shop with a GMAW robot...

That's kinda what I was thinking when I first saw it. That's why I was curious as to what equipment their shop had available without purchasing the robotics just for this.

That would sure keep a couple newbies busy learning to weld.

If you have a long enough lead time just sub it to a job shop...with this economy someone will jump on it at the right price I figure
