Abstract
A suggested welding crane for welding of objects comprises an arm, a stand and a welding head. The arm includes at least a first and a second segment, which are arranged with their length axes essentially parallelly and are telescopically movable along their length axes in relation to each other so that at least a first segment of said segments at least partly slides into at least a second segment of said segments. The welding head is arranged in a distal end of an outermost segment of the arm while an innermost segment of the arm is suspended in the stand. A linear guide is arranged on at least a first segment of said segments. A co-operating part of said at least one linear guide is arranged on at least a second segment of said segments, wherein the at least one linear guide is adapted to provide said telescopic movement.
