In order to ensure the processing quality of welding robots, the following key steps and strategies can be followed:
Part preparation and assembly: strictly control the preparation quality of parts, so that the surface quality, groove size and assembly accuracy of parts meet the welding requirements. Prepare the welding process for the robot, and strictly specify the process size, weld groove and assembly size. Use high-precision assembly tools to improve the assembly accuracy of weldments and ensure the weld tracking effect.
Weld preparation: The weld should be cleaned and free of oil, rust, welding slag, cutting slag and other debris, and weldable primer is allowed. Gas shielded welding is used for positioning welding, and the spot welding parts are polished to prevent the residual slag shell or pores of positioning welding from affecting the welding quality.
Welding process control: Equipped with a weld tracking system, the welding gun follows the welding position during welding, and the distance between the welding gun and the workpiece remains constant. Using the intelligent welding system of the welding robot, the robot's motion trajectory, welding parameters, etc. are set in the computer through software to ensure the constant welding parameters and stable welding quality.
Welding quality inspection: After the weld is cooled, the operator can observe the filling degree of the weld with the naked eye. A well-formed weld should have a surface higher than the weld surface after welding, and the weld corrugation should be smooth and beautiful. This can reduce the repair rate of the weld and ensure the quality of the weld.
