The six axis welding robot has a wide welding range, flexible joints, and easy operation due to its six degrees of freedom. This article summarizes the following common problems with six axis robots.
1. Weld size mismatch:
Weld size mainly refers to the width and excess height of the weld seam. Generally, the welding speed, current, voltage, and welding range set by the system are constant. If there is a mismatch in the weld seam, it is necessary to check the wire feeding mechanism. Worn wire feeding machines or blocked wire feeding nozzles can lead to mismatched weld size.
2. The phenomenon of welding deviation occurs:
The problem of welding deviation requires re polishing of the weld seam, which can easily lead to low production efficiency and delay in the company's production plan. The occurrence of welding deviation may be due to the inaccurate position of the welding gun. Workers can adjust the welding position and then check whether the parameters set by the system are consistent.
3. Weld spatter:
Spattering of solder joints can cause granular small spots on the welded workpiece, affecting the welding quality. If there is a phenomenon of welding spatter, it is necessary to check whether the material of the welding component meets the welding requirements or the hydrogen and nitrogen content of the welding material, whether the welding wire is too long, and in daily welding operations, choose a better gas shielded welding to prevent the occurrence of welding spatter.
4. Burn robotic arm:
Welding robots can replace humans in dangerous and harmful environments, but at the same time, they bring another problem. Although machines are not afraid of toxic gases and do not breathe, welding is a high-temperature spark sprayed out, which often "burns" the robot's arms.
In view of this situation, targeted protective covers can be added to the welding robot, and a stepped protection scheme can be adopted to ensure that the robot's welding arm and pipeline are not burned by flying sparks.
5. Injury accidents:
When welding robots are running online, accidental injuries can sometimes occur, which requires that workers must never enter the safe range of the robot's movement and ensure that there is no interference within the movement area. This is the most important principle for safety management of welding robots.
In addition, corresponding reliable measures need to be taken, such as installing protective barriers around the welding robot; Install a plug-in electrical contact switch on the safety door at the entrance of the guardrail, which can quickly cut off the power supply to the robot in case of an emergency; Install multiple emergency stop buttons near the robot workstation, which can be used for emergency shutdown in case of unexpected situations.
In daily welding operations, appropriate welding materials are selected, welding operations are carried out in sequence, welding system parameters are optimized in a timely manner, and data is updated in a timely manner to avoid problems affecting the production process of the enterprise.
The above is a summary of the common problems and solutions that six axis welding robots often encounter in daily welding work. Prevention is more important than repair. Enterprises should maintain the welding robots well in their daily use to avoid any problems that may slow down the production process.
