The application of traditional industrial robots in the welding field is mainly completed by manually teaching the welding parameters and path according to the teach pendent. Traditional teaching program is low efficiency and complex operation when dealing with some regular but repetitive welding models. A visualization programming module which could be used for regular welding was designed. This module was applied for α beam box welding combined with the independently developed welding craft. This module could generate model samples according to the key parameters of the imported model. By selecting welding path points in the samples, a robot program that could be directly used for welding was generated. The welding parameters could be changed in welding craft. The transition point can be freely modified in the robot program. The welding status could be monitored by user interface. The design can improve the application efficiency of the welding craft in the work filed, simplify the complexity of the function, and provide a high level of freedom in program editing.
