Cutting some 2 1/2" square tubing into 4 inch pieces today and I found
that the weld bead inside the tubing prevents it from being a slip fit over
the two inch tubing. My pieces are only four inches long so access isn't
really an issue. Does anyone have ideas better than a die grinder for
taking this bead off?
Can I "lay it down" with a torch? Would that take it down enough? I
forgot the inside dimension of the tubing, so the bead will obviously make
up the difference in the clearance, which is fine with me.

I made and used a broach on 1/2" tubing where access was a problem. Mine were
also short pieces, well within the capacity of my hydraulic press.

If it warrants the setup time, square both ends, then use a die sink end
mill to remove the weld. You can tailor the quality to the demand that
way.

Since the pieces are but 4" long, do it the way the old-timers would -- with
a cold chisel.
You may have to regrind your point to get the proper work angle between the
chisel and workpiece.

I do this all the time. Simply lay it flat in a vise and stick in a
course mill bastard file and give it a few passes. Since the file
sticks out both ends, its easy to apply pressure evenly.

Well, I'll be using over 20 pieces with my current project. I need to
do it cheap, and have lots of time coming up.
For multiple pieces? Not saying it won't work, but how much trouble is
anyone willing to endure to remove 4" of weld? I'd suggest that it could
prove to be a daunting task, especially if the welds have considerable
flash. That's really the key to how to make the parts fit. If the flash
is substantial, filing could get old real fast. By handling properly, each
part could conceivably be machined as I suggested in no more than two or
three minutes, with complete control.
Do keep in mind I don't like using files for anything except for deburring.
Others may enjoy their use.

BECAUSE SOMETIMES YOU CAN GET THE WELDED TUBING FOR FREE RATHER THAN
HAVING TO PAY AN ARM AND A LEG FOR IT. AND OTHER TIMES YOU MAY HAVE TO
GO MANY MANY MILES TO FIND RECEIVER TUBING AND YOU MAY HAVE SOME OF
THE WELDED KIND IN YOUR STOCKPILE.

Less filling, tastes great. Low in carbs, high in fiber and can
increase your bicep size by at least 1" in less than 90 days or your
money back!

The fastest would probably be a broach. The broach would be a single pass
solution and would happen in seconds. You'll spend more time swapping parts
than the actual work itself. Do backup the joint for more repeatable
machining.

This one I considered awhile, but all I have is air, arc, and a torch,
no machine tools. If I could secure a chisel in a smaller piece of pipe
somehow, then pound on the inside pipe/broach, I wonder how far it'd get
before I couldn't get it out anymore or broke the chisel.
I think I have a chisel for the air hammer, I'll have to see how well
that does.
I won't be able to get to this idea for a few days, I just had my
shoulder operated on yesterday and the tradeoff with being able to use both
sets of fingers in more pain. Can't win somedays... All ideas will be
entertained/attempted eventually, depending on how much I can get away with
doing when the wife isn't here to watch over me!
