Solutions to Laser Welding Defects   As industrial manufacturing develops in the direction of high-end, intelligent, and green, driven by the demand for new energy vehicles, lithium batteries, semiconductors, and emerging markets, the demand for laser welding continues to be stimulated, and the application scope and market continue to expand. Especially in the fields of consumer electronics, new energy vehicles and other fields, the requirements for laser welding are getting higher and higher, providing a huge market space for laser welding. However, any processing method will produce certain defects or defective products if its principles and processes are not mastered, and laser welding is no exception. Only by having a good understanding of these defects and learning how to avoid them can we better utilize the value of laser welding and process products with beautiful appearance and high quality. Through long-term experience accumulation, QUESTT welding application engineers have summarized some solutions to common welding defects for reference and communication by industry colleagues! 1.Crack The cracks generated in continuous laser welding are mainly thermal cracks, such as crystal cracks, liquefaction cracks, etc. The main reason is that the weld produces a large shrinkage force before it is completely solidified. Measures such as wire filling and preheating can reduce the cracks. or eliminate cracks. 2. Stomata Porosity is a defect that is easily produced in laser welding. The molten pool of laser welding is deep and narrow, and the cooling rate is very fast. The gas generated in the liquid molten pool does not have enough time to escape, which can easily lead to the formation of pores. However, laser welding cools quickly and the pores produced are generally smaller than traditional fusion welding. Cleaning the workpiece surface before welding can reduce the tendency of pores, and the direction of blowing will also affect the occurrence of pores. 3. Splash The spatter produced by laser welding seriously affects the surface quality of the weld and can contaminate and damage the lens. Spatter is directly related to power density, and appropriately reducing welding energy can reduce spatter. If penetration is insufficient, the welding speed can be reduced.   4. Undercut If the welding speed is too fast, the liquid metal from the back of the small hole pointing toward the center of the weld will not have time to redistribute, and will solidify on both sides of the weld to form undercuts. If the joint assembly gap is too large, the melted metal for filling the joints will be reduced, and it is easy to produce undercuts. At the end of laser welding, if the energy decrease time is too fast, the small hole will easily collapse, resulting in local undercut. Controlling the power and speed to match can effectively solve the problem of undercut. 5.Collapse If the welding speed is slow, the molten pool is large and wide, the amount of molten metal increases, and the surface tension is difficult to maintain the heavier liquid metal, the center of the weld will sink, forming collapses and pits. At this time, the energy density needs to be appropriately reduced to avoid The molten pool collapsed. Correctly understanding the defects produced during the laser welding process and understanding the causes of different defects can help us solve the problem of abnormal weld seams during the laser welding process in a more targeted manner.

When it comes to handheld laser welding machines, there are two main types available in the market: air-cooled and water-cooled. Both these types have their own advantages and disadvantages, and choosing the right one mainly depends on the user’s requirements. In this article, we will discuss the advantages and disadvantages of both air-cooled and water-cooled handheld laser welding machines.   Air-Cooled Handheld Laser Welding Machines   Advantages:   1. Portability: Air-cooled handheld laser welding machines are small and lightweight, making them easy to transport and use anywhere. They are also easy to handle and maneuver, making them an excellent option for small-scale welding applications.   2. Low Cost: Air-cooled handheld laser welding machines are less expensive than their water-cooled counterparts. This is because they require less complex equipment and fewer resources to operate.   3. Less Maintenance: As air-cooled handheld laser welding machines do not require complex cooling systems, they are easier to maintain. This can help save time and money on maintenance costs.   Disadvantages:   1. Lower Power: Air-cooled handheld laser welding machines have a lower maximum power output than water-cooled machines. This can be a disadvantage when working with thicker or stronger materials.   2. Limited Duty Cycle: Air-cooled handheld laser welding machines have a shorter duty cycle than water-cooled machines. This means they need to be allowed to rest for a certain amount of time after a specific period of use to prevent overheating.   Water-Cooled Handheld Laser Welding Machines   Advantages:   1. High Power: Water-cooled handheld laser welding machines have a significantly higher power output than air-cooled machines. This makes them an excellent option for welding thick or strong materials.   2. Extended Duty Cycle: Water-cooled handheld laser welding machines have an extended duty cycle, which means they can operate for longer periods without overheating. This enhances productivity and efficiency, making them a better option for larger-scale welding applications.   3. High Precision: Water-cooled handheld laser welding machines offer high precision and accuracy, making them an excellent option for working with delicate or intricate materials.   Disadvantages:   1. High Cost: Water-cooled handheld laser welding machines are more expensive than air-cooled machines. This is because they require a more complex cooling system to maintain optimum performance.   2. Lower Portability: Water-cooled handheld laser welding machines are bulkier and heavier than air-cooled machines. This makes them less portable and can be a disadvantage when working in different locations.   3. High Maintenance: As water-cooled handheld laser welding machines require a more complex cooling system, they are more challenging to maintain. This can mean higher maintenance costs and a more complex setup process.   Conclusion:   In summary, the choice between air-cooled and water-cooled handheld laser welding machines depends on the user’s requirements and the application. While air-cooled machines are lightweight, portable, and easy to maintain, they may not be suitable for higher power applications. On the other hand, water-cooled machines offer more power, an extended duty cycle, and high precision, but they come with a higher cost and complexity of maintenance. Therefore, it is essential to evaluate the pros and cons of each option before deciding which one to use in your welding applications.
