Solutions to Spatter, Burning, and Poor Welding Problems
If your spot welding machine is working but not delivering the desired quality, the cause is usually not the machine itself, but incorrect settings or inadequate system configuration.
Spot Welding Fails – Possible Causes
Insufficient Welding Current
• Weld point remains small
• Sheet metal separates easily
Solution: The current value must be readjusted according to the sheet metal thickness.
Incorrect Welding Time
• Short time → no weld
• Long time → burning and spatter
Solution: Digital time control and a prescription-based operation system should be used.
Electrode Wear or Incorrect Electrode Tip
• Current cannot be transmitted correctly
• Weld point disintegrates
Solution: The electrode tip shape and material must be suitable for the application.
Spot Welding Spattering – Causes and Solutions
Excessive Current Use
• Surface burning
• Spatter formation
Solution: Stable welding is achieved with lower current in MFDC systems.
Insufficient Electrode Pressure Force
• Sheets do not make full contact
• Melting becomes uncontrolled
Solution: Stable force should be applied using pneumatic or servo pressure systems.
Galvanized Sheet Problems
• Coating burns
• Surface deteriorates
Solution: The current–time–pressure balance must be correctly adjusted.
Spot Welding Burning – Critical Errors
• Long welding time
• Weak cooling system
• Flattening of the electrode tip
Solution: Water-cooled systems and current feedback control are essential.
