Manhart How to deal with common malfunctions during the operation of handheld laser welding machines?

**Dealing with common malfunctions during the operation of handheld laser welding machines**
1、 Insufficient laser power
Insufficient laser power is one of the common faults of handheld laser welding machines, which may lead to unsatisfactory welding results and even inability to perform normal welding work. The following are the treatment methods for insufficient laser power:
1. * * Check power supply * *: Ensure that the power supply connected to the laser welding machine is stable, and that the voltage and current meet the equipment requirements. If there is a problem with the power supply, it should be replaced or repaired in a timely manner.
2. * * Check laser generator * *: Check the operation status of the laser generator to ensure its normal operation. If the laser generator is damaged or its performance decreases, it needs to be repaired or replaced.
3. * * Clean the lens * *: Regularly clean the laser transmission lens to ensure its surface is clean, free of dust or impurities, to ensure the transmission efficiency of laser power.
4. * * Adjust parameters * *: Adjust laser power, focal length, and other parameters appropriately based on the type and thickness of the welding material to achieve the best welding effect.
2、 Unstable welding quality
Unstable welding quality may manifest as uneven welding points, discontinuous welds, and other issues that affect the strength and appearance of the welded parts. The following are methods to deal with unstable welding quality:
1. * * Check welding materials * *: Ensure that the quality and specifications of the welding materials meet the requirements, and avoid unstable welding quality caused by material issues.
2. * * Stable operation techniques * *: Operators should maintain stable operation techniques during the welding process to avoid hand shaking or instability leading to poor welding quality.
3. * * Check welding speed * *: Adjust the welding speed appropriately to ensure moderate welding speed and avoid unstable welding quality caused by too fast or too slow welding speed.
4. * * Check gas flow rate * *: Ensure stable flow rate and pressure of welding gas to avoid poor welding quality caused by insufficient or unstable gas flow rate.
3、 Equipment overheating
Overheating of equipment may cause damage or performance degradation, seriously affecting the progress of welding work. The following are methods for handling equipment overheating:
1. * * Check the cooling system * *: Ensure that the cooling system of the equipment is operating normally, and that cooling water or cooling fans and other components are in normal working condition. If there is a problem with the cooling system, it should be repaired or replaced in a timely manner.
2. * * Control working hours * *: Reasonably arrange working hours to avoid equipment overheating caused by prolonged continuous operation. When working for a long time, appropriate cooling measures should be taken, such as increasing cooling fans, reducing work intensity, etc.
3. * * Maintain good ventilation * *: Ensure good ventilation around the equipment to avoid poor heat dissipation caused by working in enclosed or narrow spaces.
4、 Control system malfunction
Control system failures may cause equipment to malfunction or operate insensitivly. The following are methods for handling control system failures:
1. * * Check the control circuit * *: Ensure that the control circuit is connected correctly and there are no open circuits or short circuits. If there is a problem with the control circuit, it should be repaired or replaced in a timely manner.
2. * * Restart device * *: Try restarting the device to see if it can solve the control system malfunction. If there is still a problem after restarting, the device should be further inspected.
3. * * Check Control System Components * *: Check all components of the control system, such as circuit boards, sensors, actuators, etc., to ensure they are in normal working condition. If the components are damaged or their performance decreases, they should be repaired or replaced.
4. * * Seeking professional assistance * *: If the above methods cannot solve the control system malfunction, professional assistance should be sought for detailed diagnosis and repair.
Summary: When dealing with common faults during the operation of handheld laser welding machines, it is necessary to first clarify the type and cause of the fault, and then take corresponding treatment methods. For faults that cannot be resolved on their own, professional assistance should be sought in a timely manner to ensure that the equipment can operate normally and safely.
