The robot welding process mainly includes welding method, welding power source, base material, welding material, gas, plate thickness (pipe diameter and wall thickness), groove form, pre-welding assembly, welding position, welding sequence, welding track, welding gun posture and welding Parameters, etc., before formulating the robot welding process, you must first have a full understanding of the welded workpiece and welding materials, and then the weldability of the weldment material, blanking, forming processing technology, assembly method selection, and robot welding trajectory, Analyze posture, welding torch angle, welding parameters, etc., determine welding focus and difficulties, and formulate solutions to achieve the goals of controlling welding quality, improving efficiency, and reducing costs.
According to the technical requirements of the weldment, through process analysis, the robot welding process knowledge is used to formulate the robot's welding plan, and fully consider the welding sequence, the processing of key points, the welding gun angle and the robot's posture. After the robot welding path and posture programming is completed, the welding parameters are set and adjusted, and the welding process test is completed; finally, the process schemes are compared in terms of quality, efficiency and cost, and the best scheme is selected.
Robot welding also brings a lot of new challenges: ① The preparation quality of the workpiece and the precision of the weldment assembly are high. ②When designing the structure and welding process of the workpiece, the accessibility of the welding torch, the number of flips of the positioner, etc. should be considered. ③The investment amount is high and the payback period is long. ④ The power of the power supply must meet the characteristics of high output and high stability required by robot automatic welding. In addition, robot welding has higher requirements for operators and requires a higher comprehensive quality; in order to obtain high-quality welds, it is particularly important to formulate accurate and reasonable robot welding processes.
