Although welding robots have brought convenience to various fields, the production efficiency has also been improved accordingly. However, the welding robot should also pay attention to the use of welding tools. For example, the selection of welding wire has welding positioner and fixtures, etc., which will affect the welding robot. The following editor will explain to you what impact welding tools will have on welding robots.
1. The influence of robot welding positioner and fixture on welding
1) Higher requirements for the positioning accuracy of the parts, the relative position accuracy of the weld is higher, which should be 1mm.
2) Since weldments are generally assembled by multiple simple parts, and the assembly and positioning welding of these parts are carried out in sequence on the welding fixture, therefore, their positioning and clamping are carried out individually. .
3) The positioning of the robot welding fixture before and after the process must be consistent.
4) Due to the relatively large displacement angle of the positioner, the robot welding fixture should avoid the use of movable manual bolts as much as possible.
5) The robot welding tooling fixture should use fast compression parts as much as possible, and it needs to be equipped with a platform with holes. In order to fasten the compression clamp tightly.
6) Unlike ordinary welding jigs, robot welding jigs can not only weld the front side, but also weld the workpiece on the side, which can extend infinitely.
The above six points are the main differences between robot welding fixtures and ordinary welding fixtures, which have a direct impact on the quality of robot welding.
2. The influence of welding wire on the welding process of welding robot
The robot can choose barreled or coiled welding wire as required. In order to reduce the frequency of replacing the welding wire, the robot should use barreled welding wire. However, due to the barreled welding wire, the wire feeding hose is very long and the resistance is large, which requires high quality such as the stiffness of the welding wire. When a welding wire with a poor copper plating quality is used, the copper plating on the surface of the welding wire will reduce the internal volume of the pipe due to friction, and the resistance will increase during high-speed wire feeding. The welding wire cannot be sent out smoothly, resulting in jitter, which makes the arc unstable and affects welding. Sewing quality. In severe cases, a jam will occur and the robot will stop, so the wire guide must be cleaned in time.
