Why can laser welding machines accurately weld tiny parts?
Laser welding machines can accurately weld tiny parts for the following reasons:
1. High energy density: The laser beam generated by the laser welding machine has a high energy density, allowing the laser energy to be highly concentrated. In this way, during the welding process of tiny parts, energy can be quickly transferred to the material to achieve precise welding.
2. Fine spot: The spot of the laser beam can be very fine, which allows laser welding to operate in specific areas of tiny components to achieve precise control.
3. Adjustable welding parameters: The welding parameters of the laser welding machine (such as power, speed, pulse frequency, etc.) can be adjusted according to actual needs, so that the welding process can be optimized for the characteristics of small components.
4. Non-contact welding: Laser welding is non-contact welding, which avoids direct contact between the equipment and the workpiece, and reduces the risk of deformation and damage of small components during the welding process.
5. Short welding time: Laser welding has the characteristics of short welding time, which can reduce the exposure time of small parts to high temperatures and reduce the heat-affected area, thereby maintaining the integrity and accuracy of the parts.

What are the differences between water-cooled and air-cooled laser welding machines?
The main difference between water-cooled and air-cooled laser welding machines is the cooling method. Here are some key differences between them:
1. Cooling medium:Water-cooled laser welding machines use water as the cooling medium and reduce the temperature of the equipment through a circulating water cooling system. Air-cooled laser welding machines use air as the cooling medium and take away the heat through fans.
2. Cooling effect:The cooling effect of water-cooled laser welding machines is usually better than that of air-cooled ones because the heat conductivity of water is better than that of air. This means water-cooled equipment remains better stable when operating at high power, resulting in improved welding quality and efficiency.
3. Equipment volume and weight:Water-cooled laser welding machines require a circulating water cooling system, so the size and weight of the equipment are usually larger. The air-cooled laser welding machine is relatively lightweight and easy to carry and move.
4. Energy consumption:The energy consumption of water-cooled laser welding machines is relatively low because the water cooling system can be recycled, reducing energy waste. Air-cooled laser welding machines need to continuously consume electricity to drive the fan, and the energy consumption is relatively high.
5. Noise:During the operation of the air-cooled laser welding machine, the fan will produce a certain amount of noise. The noise of water-cooled laser welding machines is relatively low because the water circulation system makes almost no noise when working.
6. Maintenance costs:Water-cooled laser welding machines require regular replacement of cooling water and clean water circulation systems, and maintenance costs are relatively high. Air-cooled laser welding machines are low maintenance and only require regular cleaning of the fan and filter.
7. Application scenarios:Water-cooled laser welding machines are suitable for high-power, long-running working environments, such as large manufacturing enterprises. Air-cooled laser welding machines are suitable for small businesses or situations that require portable equipment.
