How is seamless metal tubing made?
« on: 16/10/2008 09:02:32 »
j s  asked the Naked Scientists:

Chris et al,

I have a question of geometry and industrial processes:  How do they make seamless metal tubing?  Is Scarborough Faire somehow involved?

John in San Diego

What do you think?

I worked in a steel tubing factory for sometime and the tube wasnt really "seamless" but where it was welded the extra burr was cut off with a carbon blade making the tube smooth.
The tube was electric arc welded fusing the two ends of the metal together and as far as I know the weld is stronger then the rest of the tube.
