1. The welded joint is not firm
Cause of the problem: The size, shape or welding pressure of the welded joint is inappropriate, and there are impurities or bubbles during the welding process.
Solution: According to the size and shape of the welded joint, adjust the welding parameters and ensure the welding pressure is appropriate; clean the welding area to ensure there are no impurities or bubbles.
2. Oxidation of the weld surface
Cause of the problem: There is an oxidation reaction during the welding process, or the welding material is of poor quality.
Solution: Control the atmosphere during the welding process and maintain a suitable inert gas environment; check the quality of the welding materials to ensure that they meet the requirements.
3. Slag splash occurs during welding
Cause of the problem: The welding material contains impurities, there are impurities or bubbles around the weld, and the welding parameters are unreasonable.
Solution: Ensure that the quality of the welding materials meets the requirements, clean the welding area regularly; adjust the welding parameters according to the requirements of the welding materials and workpieces.
4. Welding perforations occur during the welding process
Cause of the problem: The welding current is too large, the welding speed is too fast, and the welding pressure is inappropriate.
Solution: Appropriately adjust the welding current and speed to ensure that the welding parameters meet the requirements; adjust the welding pressure to maintain appropriate pressure.
5. Welding slag appears during welding
Cause of the problem: The welding material is of poor quality and the welding area does not feel clean.
Solution: Check the quality of welding materials to ensure they meet the requirements; clean the welding area completely to ensure there are no impurities.
6. The welding speed is unstable during the welding process
Cause of the problem: The welding mechanical system is loose, the shape of the welding material is inconsistent, and the welding parameters are unreasonable.
Solution: Check the welding mechanical system to ensure there is no looseness; select welding materials with consistent shapes; adjust the welding parameters according to the welding requirements.
7. The welding area is overheated during welding.
Cause of the problem: The welding current is too large, the welding time is too long, and the welding material or workpiece is too weak.
Solution: Appropriately reduce the welding current and time to avoid overheating; check the quality of welding materials and workpieces to ensure compliance with requirements.
8. The welding machine makes too much noise during the welding process.
Cause of the problem: The welding machinery system is loose, the welding current is unstable, and the working environment is unreasonable.
Solution: Check the welding mechanical system to ensure there is no looseness; adjust the welding current to maintain stability; improve the working environment and reduce noise.
9. The welding arc is unstable during the welding process
Cause of the problem: The power supply is unstable, the welding current is unreasonable, and there are impurities in the welding electrode or workpiece.
Solution: Ensure that the power supply is stable and meets the requirements; adjust the welding current to maintain stability; clean the welding electrode and workpiece to ensure that there are no impurities.
10. The temperature of the welding machine is too high during the welding process
Cause of the problem: The welding machine has poor heat dissipation, the working environment temperature is too high, and the working time is too long.
Solution: Make sure the welding machine has good heat dissipation and clean the radiator regularly; improve the working environment and lower the temperature; control the working time to avoid being too long.
