For the welders out there.
When you replace a tube in a fuselage, what is your technique? For example, once you've cut the old tube out, do you grind the old weld off down to the original tube profile or do you leave some of the old weld in place to be sure you haven't ground into the longeron? What about replacing a tube in the middle of a cluster? Once the new tube is in place and welded, do you add a finger patch. AC 43.13 has lots of great info on repairing tubes but not a lot on replacing them.
Thanks
