Tubing must be square and burr-free to ensure
repeatable, high-quality autogenous fusion welds. Cut
the tubing to length with a hacksaw or tube cutter. Face
the tube ends with a lathe or a portable facing tool.
Deburr the ends, making sure that both the inside and
outside diameters are square and burr-free. Clean the
tube ends using an appropriate solvent.
