With the rapid development of intelligent manufacturing, the application of robot fiber laser welding machine in industrial production will become more and more extensive. However, in practical applications, welding quality is still affected by many factors. In order to achieve consistency and stability in welding quality, enterprises need to focus on the quality of welding workpieces, the accuracy of positioners and fixtures, and the selection and maintenance of welding wires. This article will explore these key factors in depth.
What are the effects of welding workpieces on robot fiber laser welding machine?
At present, most robot fiber laser welding machines use teaching programming to operate, so the assembly quality and accuracy of workpieces must maintain a high degree of consistency. In order to meet the welding quality standards, the quality of part preparation and the assembly accuracy of weldments can be improved from the following aspects:
1. Formulate special welding process standards, strictly specify part size, weld groove and assembly tolerances, and generally control the size error of parts and grooves within ±0.8mm, and the assembly size error should be less than ±1.5mm to reduce weld defects.
2. Use high-precision assembly tools to improve the assembly accuracy of weldments.
3. The weld surface should be clean, free of impurities such as oil, rust, and welding slag to improve the success rate of arc initiation. Gas shielded welding should be used for positioning welding, and the spot welding parts should be polished to avoid arc stability affected by welding slag or pores.
How do welding robot positioners and fixtures affect welding quality?
When welding robots are operating, the accuracy of positioners and fixtures is crucial. The following points need to be focused on:
1. The positioning accuracy of parts is required to be high, and the relative position accuracy of welds should be controlled at ≤1mm.
2. Since weldments are usually welded together by multiple parts, positioning and clamping need to be performed in sequence.
3. When the positioner has a large flip angle, the use of movable manual pins should be avoided as much as possible to prevent position deviation during welding.
4. Robot welding fixtures should give priority to quick clamping parts and be equipped with a platform with holes for quick clamping.
5. Compared with ordinary welding fixtures, robot welding fixtures can not only perform front welding, but also side welding, greatly improving welding flexibility.
What is the impact of welding wire quality on the welding effect of robot fiber laser welding machine?
Robot fiber laser welding machine can choose barreled or coiled welding wire according to needs. Since barreled welding wire can reduce the frequency of replacement, it is more popular on automated production lines. However, long-distance wire feeding places higher requirements on welding wire quality:
1. The stiffness of the welding wire must be sufficient to reduce the resistance during wire feeding.
2. Low-quality copper-plated welding wire May cause the copper layer to fall off due to friction and accumulate inside the conduit, increasing the wire feeding resistance and affecting welding stability.
3. Unsmooth wire feeding will cause arc jitter and even jamming. In severe cases, it May cause the robot fiber laser welding machine to stop, so the wire conduit needs to be cleaned regularly.
How to reduce robot fiber laser welding machine failures and improve production efficiency?
In order to reduce the failure rate of robot fiber laser welding machine in production, the following measures can be taken:
1. Use high-quality fixtures to improve the assembly accuracy of parts.
2. Strictly control the quality of weldment preparation to reduce the occurrence of weld defects.
3. Choose high-quality welding wire to reduce wire feeding resistance.
4. Regularly maintain the welding robot, clean the wire guide tube to prevent blockage.
In addition, our robot fiber laser welding machine is a highly flexible 6-axis robot that can complete the welding of complex workpieces and can adapt to the changing situation of workpieces. The laser system can use welding lenses, cutting lenses, scanning welding lenses and even laser cladding heads. Due to the magnetic coupling connection method, different lenses can be quickly switched. It is also called a robot laser welder or a laser beam welding robot. The full name of laser beam welding is LBW, so you can also call it an LBW robot. If you want to learn more about our products, please visit our website.
