Arc welding robots are automated mechanical equipment used for welding operations. In order to improve welding quality, more and more enterprises are choosing arc welding robots for welding. The major difference between arc welding robots and traditional welding is that intelligent systems control and maintain welding stability. Let's take a look at how arc welding robots can achieve welding stability together!

1. Inspection work before welding

In order to ensure welding stability, it is necessary to inspect the body of the argon arc welding robot for loose screws and perform daily cleaning work to check the compatibility of the welded workpiece with the argon arc welding process.

2. Adjust welding current

Welding current is the circuit current that flows through the welding rod and wire during welding. When setting the welding current, it is necessary to refer to the specifications of the weld seam and the depth and width of the weld seam. Excessive or insufficient welding current can affect the welding quality. If the welding current is too small, it is not easy to start an arc, and the arc is prone to instability during the welding process, resulting in welding defects. If the welding current is too large, the weld seam depth and width will be large, causing welding spatter and waste.

When adjusting the welding current, it is possible to increase the welding current appropriately and improve the welding efficiency while ensuring the welding quality.

3. Adjustment of welding voltage

The adjustment of welding voltage needs to be matched with the current. When the welding current is low and the voltage is high, the welding robot is prone to welding spatter and workpiece deformation during the welding process. Only when the voltage is low, the welding process becomes relatively stable, which can make the weld well formed and facilitate the use of welding robots for thin plate welding in enterprises.

4. Mechanical arm movement speed

The motion control system of a welding robot mainly consists of a program interpreter, motion interpolator, servo driver, and other auxiliary modules, ensuring that the welding robot maintains welding accuracy during the motion. The setting of motion speed can be done in the control system, which can be combined with the weld specifications of the workpiece to be welded.

5. Ensure welding quality after welding

After welding is completed, the welding robot uses instruments to inspect the weld seam, which is beautiful and firm. After welding is completed, the operator can perform daily cleaning and maintenance work for stable operation in the future.
