Abstract
A new technology of double-sided arc welding (DSAW) in which gas metal arc welding (GMAW) is employed for root welding and filler passes was proposed in this paper. The realized master–slave mode, dual-robot collaboration provides the asymmetric and symmetric welding for root welding and filler passes, respectively, by two robots from both sides of the thick plate. Then, the multi-pass path planning was put forward, and Roboguide was used to verify the feasibility of the planning. Finally, welding experiment was conducted. The results indicate that the good comprehensive properties in tensile strength, bend property, impact toughness, and hardness were obtained. This new technology can realize no back chipping for thick plate welding. Furthermore, it has the potential advantages for the implementation of automatic welding for thick plate.
