When the laser power of a handheld welding machine decays, it can affect several aspects of the welding quality, including but not limited to the following:
1. **Weld Depth & Strength**:
– **Impact**: Power degradation can cause the weld pool to not be deep enough and the weld strength to decrease, which may not achieve the expected structural strength.
– **Result**: Weldments may break or fall off during use, affecting the reliability and durability of the product.
2. **Weld appearance**:
– **Impact**: Insufficient laser power may lead to uneven weld surface and welding defects, such as porosity, cracks, slag inclusions, etc.
– Result: The weld does not look good and may require additional sanding and trimming, increasing the cost and time of machining.
3. **Welding Speed**:
– **Impact**: Power decay will reduce the welding speed because the welding speed needs to be slowed down to guarantee the quality of the weld.
– Result: Reduced production efficiency, affecting overall production planning and schedule.
4. **Heat-Affected Zone**:
– **Impact**: Power degradation can lead to an expansion of the heat-affected zone, increased material deformation, and more severe welding distortion and stress concentration problems.
– Result: The dimensional accuracy and shape of the weldment may be affected and additional correction and treatment will be required.
5. **Joint Reliability**:
– **Impact**: Due to insufficient weld depth, the metallurgical bonding of the welded joint becomes poor, and the reliability of the joint is reduced.
– **Result**: Welded joints are prone to failure when subjected to load, affecting the overall performance and safety of the product.
6. **Material Adaptability**:
– **Impact**: Power degradation can limit the adaptability of the welding machine to different materials, especially those with high reflectivity or high thermal conductivity.
– Result: Certain materials may not be welded effectively, limiting the range of applications of the welding machine.
7. Energy Efficiency:
– Impact: Power degradation means that the same energy input is converted into effective laser energy less efficiently.
– Result: Increased energy consumption, reduced energy efficiency of equipment, and increased operating costs.
In order to avoid the above problems, it is necessary to inspect and maintain the welding machine in time to ensure that the laser power is stable within the specified range. Measures such as regular cleaning of lenses, replacement of aging parts, and checking of cooling systems and power supply can effectively prevent power degradation and ensure weld quality.
