Welding tool and method of using a welding tool

A welding tool comprising:

• a support structure;
• a welding torch coupled to the support structure and configured to rotate relative to the support structure about a welding axis, wherein the welding axis is defined by rotation of the welding torch relative to the support structure;
• and
• a locating device coupled to the support structure and movable between a retracted position and an extended position, wherein in the extended position an end of the locating device is closer to the welding axis than in the retracted position such that a perpendicular distance between the end of the locating device and the welding axis when in the retracted position is greater than the perpendicular distance between the end of the locating device and the welding axis when in the extended position, wherein the perpendicular distance is a distance along a line extending from the end of the locating device and intersecting the welding axis at a right angle, and wherein the locating device comprises a recess at the end and is configured such that, when an object to be welded is positioned at least partially within the recess of the locating device in the extended position, the welding axis passes through the object to be welded.
