摘要： 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.

摘要： A pipe crawling welding device including a welding module having a welding head thereon, a mounting shaft, a crawler module and a boom is disclosed. The boom may be fixedly coupled to the mounting shaft. The crawler module may be rotationally coupled to the mounting shaft via, for example, first and second ring bearings so that the crawler module may rotate with respect to the mounting shaft. The welding module may be fixedly coupled to the mounting shaft so that in use, the welding module, boom and mounting shaft may rotate in an opposite direction and at a same rotational speed relative to a direction and rotational speed of the crawler module to maintain an angular position of the welding head.
