Common faults and solutions that may occur during the use of welding robots include but are not limited to the following:
1.Power supply problem
○Cause of failure: The power voltage is unstable or there is a problem with the power line.
○Solution: Make sure the power supply system is stable and use a voltage regulator; check and repair the power cord connection to ensure good contact.
2. Welding deviation or inaccurate position
○Cause of failure: Workpiece assembly deviation, TCP (Tool Center Point) setting is inaccurate.
○Solution: Recheck and correct the assembly accuracy of the workpiece; adjust and update TCP parameters to ensure accurate positioning of the welding gun.
3. Gun collision phenomenon
○Cause of failure: programming path error, sensor failure or workpiece clamping position change.
○Solution: Reteach or modify the program to avoid collision; check and repair or replace the sensor; enhance the stability of workpiece positioning.
4. Arc fault (cannot ignite arc)
○Cause of failure: The welding wire is not in contact with the workpiece, the welding current is too small, the protective gas supply is insufficient, or the welding wire contact tip is worn.
○Solution: Confirm that the welding wire is in correct contact with the workpiece; adjust welding process parameters such as current, voltage, etc.; check the gas path system to ensure sufficient gas flow; replace worn contact tips in a timely manner.
5.Welding defects
○Such as undercuts, pores, cracks, excessive spatter, etc.
○Solutions:Adjust welding parameters according to specific defect types, such as current size, welding speed, gas flow, etc.; improve the welding process, such as changing the welding sequence, increasing the preheating process or using suitable filling materials; cleaning the oil dirt and rust in the weld area to ensure a good welding environment.
6. Mechanical component failure
○Such as poor lubrication of motors, reducers, shaft joints, damaged transmission components, etc.
○Solution: Perform regular mechanical maintenance, including cleaning, lubrication, and replacement of worn parts; inspect parts with abnormal sounds or vibrations, and ask professionals to repair or replace them if necessary.
7. Control system failure
○Such as controller crash, communication interruption, software error, etc.
○Solution: Restart the device, restore factory settings or update the software version; check whether the hardware interface connection is firm and whether the cable is damaged; contact the manufacturer's technical support for a solution.
