Shipbuilding I-beam Welding Robot with 6-Axis Cobot and Integrated Torch The AUBO I16H shipbuilding I-beam welding robot is a six axis collaborative welding cobot developed for demanding shipbuilding and heavy steel fabrication. With a 16 kg payload, a 967.5 mm reach and an integrated welding torch package, it reaches deep into I-beam webs and stiffener intersections where access is tight and weld quality is critical. The cobot format lets shipyards automate repetitive I-beam
