Laying the foundation for innovation, welding technology has transformed structural fusion over the years. Its history dates back to the Bronze Age when the same welding procedure was used to create small gold boxes. However, with advancements, the current market value of the welding industry has reached $23 ten 100 million.
Laser welding is the most modern welding technology method of this era. The utilization of various high-power lasers and focusing tools can drive the development in terms of functionality of laser welders. In the next generation, the demand for air-cooled laser welders is expected to exceed that of water-cooled models. This is Due to the widespread demand for compact and lightweight welding equipment across multiple industry sectors.
Detailed explanation of air-cooled welding technology
With a typically small structure, air-cooled welders are compact and high-performance welding equipment. They use air as the main factor to assist welding. These are also ideal for a wide range of applications.
physical basis
The physical basis of air-cooled welding is as follows:
The laser source generates a high-power beam. It is then focused on the welding area through the optical focusing lens used.
The heat source, usually generated by a laser beam, helps melt the matrix as well as the filler metal.
To prevent cracking and warping in areas where heat is concentrated, compressed air is now applied to the heated area.
This fuses the two parts of the metal together and holds them in place. After this, it is allowed to cool so that it retains the desired shape without deforming.
Equipment structure and key components
To better understand the structure and components of an air-cooled laser welder, we describe its prominent parts below.
Laser Source – This is the main component of the machine. It produces a laser beam that drives the entire process forward.
Welding Head – It houses the laser source. It is interconnected with the scanner and optical lens. It helps in focusing the laser beam on the corresponding area.
Scanner – It can be galvanometer related or mechanical. It helps in moving the laser beam over the welding area.
Cooling system – uses air compression. It also helps the laser avoid unnecessary heating.
Control Center – Laser power, speed, density, and output are all set by this. It manages all operations.
advantage
1. The device is simple to use. Easy to set up and assemble.
2. The air-cooled laser welding machine is low in price and is an ideal choice for mass production by small and medium-sized enterprises.
3. These are high-speed equipment, suitable for fast work.
4. It is a multi-functional welding machine that can be used in many industries such as automobile and manufacturing.
5. Since compressed air replaces water coolant, it is lightweight. It is very portable, and can be used in many fields.
6. The air-cooled welder does not need to replace the coolant. This makes it simple and convenient to use.
shortcoming
1. Due to long-term continuous operation, there may be potential heat accumulation. If the heat is not dissipated correctly, this can easily cause the drive to malfunction.
2. If this welding machine uses a strong airflow fan, it will produce some noise, which may be an obstacle
Detailed explanation of water cooling welding technology
Water-cooled welding is a powerful and high-stress resistant technology that uses water as a cooling aid during welding. The welding machines used for this purpose are heavy but can produce the desired results without oxidation of the material. It has a unique range of applications in multiple business sectors.
Working principle of water-cooled laser welding machine
Water-cooled welding techniques draw coolant through a pump located within the radiator. This is usually contained in or close to the power supply. It is collected in the handle through cooling tubes in the power cord. The coolant is circulated back to the radiator. Here, the coolant is captured The heat is dissipated through the deflection process of the heat sink. In addition, the surrounding air and shielding gas help disperse the radiation of the arc.
physical basis
The physical basis of a water cooling system is as follows:
Due to its excellent specific heat capacity, water serves as an effective coolant.
The cooling system is the core part of cooling the laser source.
The pump continuously delivers water inside the cap.
It absorbs the residual heat of the laser and releases it slowly.
After the cooling process, the water is pumped back into the system.
advantage
1. Water-cooled laser welding machines are widely used in many industrial applications due to their rapid cooling mechanism. This also produces original and precise welds because there is no excessive buildup due to water.
2. The machine is considered highly stable because the coolant can cool it down instantly.
3. This tool generally has high durability and a service life of about 5 years. Its components have a longer service life than those of other laser welding machines.
shortcoming
1. One disadvantage of this welding machine is that it is expensive.
2. In addition, operating costs are high.
3. After a period of use, the coolant needs to be replaced and the equipment needs to be cleaned. Due to high maintenance costs, it is not ideal to use.
4. Water-cooled machines are heavy and not suitable for movement, which reduces their convenience.
5. Due to the large amount of electricity used by the water cooling system, the overall power consumption of these devices is too high. This means that the total power consumption is quite large and not environmentally friendly.
