Common Problems And Solutions During The Use Of Welding Robots

Undercut problem occurs: it may be due to improper selection of welding parameters, wrong welding torch angle or welding torch position, which can be adjusted appropriately.

Pore problem: It may be caused by poor gas protection, too thick primer on the workpiece, or insufficient drying of the protective gas, and it can be solved by making corresponding adjustments.

There is a problem of welding deviation: it may be that the position of the welding is not correct or there is a problem when the welding torch is found.

At this time, it is necessary to consider whether the TCP (midpoint position of the welding torch) is accurate and adjust it. If this happens frequently, check the zero position of each axis of the robot, and re-calibrate to correct it.

Too much spatter: It may be due to improper selection of welding parameters, gas composition or too long extension of the welding wire. You can properly adjust the power of the machine to change the welding parameters, adjust the gas proportioner to adjust the proportion of the mixed gas, adjust the welding torch and The relative position of the workpiece.

An arc crater problem is formed after cooling at the end of the weld: when programming, add the submerged arc crater function in the work step to fill it up.

During the welding process, common failures of robot systems

Gun collision: It may be due to the deviation of the workpiece assembly or the inaccurate TCP of the welding torch. You can check the assembly or correct the TCP of the welding torch.

There is an arc fault and the arc cannot be struck: it may be because the welding wire does not touch the workpiece or the process parameters are too small. You can manually feed the wire, adjust the distance between the welding torch and the weld, or adjust the process parameters appropriately.

Shielding gas monitoring alarm: There is a fault in the cooling water or shielding gas supply, check the cooling water or shielding gas pipeline.

With the development of manufacturing technology, it has become an inevitable trend to realize the automation, flexibility and intelligence of welding product manufacturing.

At present, the use of robot welding has become the main symbol of the modernization of welding automation technology. Welding robots have received more and more attention due to their advantages of strong versatility and reliable work.
