How to Solve Welding Robot's Edge Biting Phenomenon


I.Reasons for Edge Biting Phenomenon

Edge biting is a common problem in robot welding,mainly manifested as protrusions or gaps at the welding point,and severe cases can even cause the welding seam to crack.So what are the reasons for the edge biting phenomenon?Below are several reasons:

Welding current is too high or too low

Welding current is an important parameter that affects welding quality.If the welding current is too high or too low,it will cause the welding temperature to be too high or too low,which will affect the welding quality and cause edge biting.

Welding speed is too fast or too slow

Welding speed is also an important parameter that affects welding quality.If the welding speed is too fast or too slow,it will reduce the welding quality and cause edge biting.

Incorrect welding posture

Welding posture refers to the angle and distance between the welding electrode and the workpiece.If the welding posture is incorrect,it will affect the welding quality and cause edge biting.

Mismatched welding parameters

During the welding process,different welding parameters need to be set according to different welding process requirements,such as welding current,welding speed,welding time,etc.If the welding parameters are mismatched,it will affect the welding quality and cause edge biting.

Unclean workpiece surface

During the welding process,if there are impurities such as oil and rust on the surface of the workpiece,it will affect the welding quality and cause edge biting.

The above are several reasons for the edge biting phenomenon in robot welding.For these reasons,we can take some measures to solve the problem of edge biting.

II.Solutions

Adjust welding parameters

According to the problem of undercut during welding,the undercut can be solved by adjusting welding parameters.For example,welding current,welding speed,welding time and other parameters can be adjusted to match the welding process requirements,thereby improving welding quality and avoiding undercut.

Change welding posture

Welding posture is one of the important factors affecting welding quality.If the welding posture is not correct,it will affect the welding quality and cause undercut.Undercut problem can be solved by changing welding posture,such as adjusting welding angle,welding distance,etc.

Clean the surface of the workpiece

During welding,if there are impurities such as oil and rust on the surface of the workpiece,it will affect the welding quality and cause undercut.The surface of the workpiece can be cleaned by cleaning and polishing to avoid undercut.

Optimize welding path

Welding path is one of the important factors affecting welding quality.Undercut problem can be solved by optimizing welding path,such as adjusting welding path,using multi-layer welding,etc.

Replace welding electrode

In the robot welding process,the selection and use of electrodes are also important factors affecting welding quality.If the electrode is used for a long time,it will cause wear and fatigue on the surface of the electrode,which will affect welding quality and cause undercut.Regularly replacing the electrode can improve welding quality and avoid undercut.



In summary,undercut in robot welding is one of the important factors affecting welding quality and needs to be solved promptly.In the actual welding production process,undercut problem can be solved by adjusting welding parameters,changing welding posture,cleaning the surface of the workpiece,optimizing welding path,replacing welding electrode,etc.This can improve welding quality,ensure the stability and consistency of welding results,and provide more stable and reliable guarantee for the production of enterprises.
