Systems and methods are provided for a boss welding positioning tool. The boss welding positioning tool may, at least, include a purge base, a purge gas delivery connector, and features for aligning two items to be welded together. The purge gas delivery connector may be configured to be coupled to the purge base and may include ports that receive purge gas and deliver purge gas to an inner portion of the items to be welded.

A method for processing an edge of a tube using an abrading apparatus is disclosed. The abrading apparatus includes a rotational symmetry axis and a chassis comprising an input side, an output side opposite the input side, and an input coupler on the input side of the chassis. The input coupler is coaxial with the rotational symmetry axis. The abrading apparatus also includes a centering member, coupled to the output side of the chassis and coaxial with the rotational symmetry axis, and abrasive members, coupled to the output side of the chassis. The abrasive members define an abrasive face radially spaced outwardly from and generally symmetric about the rotational symmetry axis and facing in a direction generally parallel to the rotational symmetry axis.
