Welding robots are industrial robots engaged in welding (including cutting and spraying). According to the International Organization for Standardization (ISO) definition of an industrial robot as a standard welding robot, an industrial robot is a multi-purpose, reprogrammable automatic control Manipulator with three or more programmable axes for use in the field of industrial automation. In order to adapt to different uses, the mechanical interface of the last axis of the robot is usually a connecting flange, which can be connected to different tools or end effectors. The welding robot is equipped with a welding clamp or welding (cutting) gun on the final shaft flange of the industrial robot to enable it to weld, cut or thermal spray. So what about the welding defects of welding robots?
Welding Robot Defects and How to Solve Them
Welding robots are an essential part of modern manufacturing processes, providing high-speed and high-precision welding capabilities. However, even the best welding robots can experience defects that can lead to sub-optimal results and increased production costs. In this article, we will explore some of the most common welding robot defects and how to solve them.
1. Edge biting
Edge biting is a common defect that can occur due to welding parameters, gun angle, or incorrect gun-to-workpiece orientation. You can adjust the power to change welding parameters, adjust the gun's attitude, and the relative direction of the gun and workpiece.
2. Welding direction
Incorrect welding direction or incorrect gun welding can cause welding deviation. In this case, it is necessary to consider the direction of the gun's center point and make adjustments. If this happens frequently, check the zero positions of the welding robot's axes and correct them from scratch.
3. Spatter
Excess spatter can occur due to improper welding parameter selection, gas composition, or excessive wire extension time. You can adjust the welding robot's power to modify the welding parameters, adjust the gas mixer to adjust the gas mixture ratio, and adjust the direction of the gun relative to the workpiece.
4. Porosity
Poor gas protection, excessive workpiece primer thickness, or boring protective gas can cause pores to form. You can handle it through the corresponding adjustments.
5. Arc pit
After cooling, an arc pit forms at the end of the weld. You can add the embedded arc pit function in the programming steps to fill it.
In conclusion, welding robot defects are common and can lead to unwanted results. However, with proper adjustments, many of these defects can be easily resolved. By staying vigilant, you can ensure that your welding robot produces high-quality welds and meets or exceeds your production goals.
