Part 3: What are the Components and Parameters of Laser Handheld Welding Machine?
The core components of the handheld laser welding machine include a laser generator, optical fiber transmission system, laser welding head, control system and cooling system. There are some suggestions for choosing a handheld laser welding machine.
3.1 Laser Type
There are four types of lasers available for laser machine. Fiber laser sources are one of the most efficient and safest laser sources.
The laser sources commonly used in handheld laser welding machines include the following:
Fiber laser uses optical fiber as the laser medium, which has the advantages of high efficiency, high reliability, compactness, and easy integration. Fiber lasers are widely used in industries such as auto parts, aerospace, and communication equipment.
CO2 laser is a laser source based on CO2 gas discharge, which has the characteristics of high power, good beam stability, and adjustable laser spot size. CO2 lasers are mainly used in non-metal, plastic, paper, PVC processing and other fields.
Photodiode lasers use the recombination process of electrons and holes to generate laser light, which has the advantages of high efficiency, small size, and low power consumption. Photodiode lasers are mainly used in communication, display devices etc.
Nd:YAG laser is a solid-state laser, which uses Nd:YAG crystal as the laser medium, and has the characteristics of high power, short pulse, and high beam quality. Nd:YAG lasers are mainly used in precision processing, medical beauty and other fields.
Other lasers: There are some other types of lasers, such as semiconductor lasers, argon ion lasers, copper vapor lasers, etc.
3.2 Parameters of handheld laser welding machine
Laser Pulse Frequency
Laser pulses are determined in Hertz (Hz). Higher frequencies produce smaller outputs. Therefore, a perfect weld requires a constant flow of sufficient energy.
Laser Pulse Waveform
When a high-intensity beam is projected onto the material surface, the metal surface will reflect and lose about 60~98% of the laser energy, and the reflectivity will vary with the surface temperature.
The power density is high, and the surface can be heated to the boiling point within the time range of microseconds, resulting in a large amount of vaporization. Therefore, the high power density mainly used in material removal such as cutting, punching and engraving. And for low power density, it is easy to form a good fusion weld.
Laser Pulse Width
Longer pulse widths can provide a higher average power over the duration of the pulse. This can be useful for welding thicker materials and increasing the penetration depth of the weld.
The optimal pulse width for a laser welding machine will depend on the specific materials being welded, the desired weld quality and strength, and other factors such as the laser’s power and wavelength. It is important to carefully select and control the pulse width to achieve the best possible welding results.
It is not only an important parameter different from material removal and melting, but also the main parameter that determines the volume and cost of laser equipment.
3.3 The Components of the Laser Welding Machine
The laser generator is the core component of the laser welding machine, which determines the power and energy efficiency of the welding machine. When choosing a laser generator, you need to consider your welding needs and budget. Higher power laser generators can weld thicker materials, but also come with higher price and energy consumption. At present, the most used power of handheld welding machine is 1000W/1500W/2000W.
Fiber Delivery System
The fiber optic delivery system is responsible for transmitting the laser beam from the laser generator to the welding head. Choosing the right fiber optical system can help you improve welding quality and stability. You need to consider transmission distance and transmission efficiency.
Laser Welding Head
The welding head is another important part of the handheld laser welding machine. You need to choose a laser head that suits your welding needs. For example, for smaller welding tasks, you can choose a smaller welding head. The welding head is divided into swing head, upper wire feeding and lower wire feeding. You can choose according to your needs. Prices may vary based on your selections.
The control system can help you control the parameters and details in the welding process. You need to choose a control system that is easy to operate and control to ensure that you can obtain high-quality welding results.
The welding process generates a lot of heat, so a cooling system is required to maintain the stability of the equipment. You need to choose an efficient cooling system to ensure the normal operation of the equipment in the high temperature environment. Handheld metal laser welding machine often use cooling systems such as water cooling and air cooling.
Part 4: Pulse Laser or Continuous Wave Laser?
Your laser welding machine can be equipped with one of two lasers, the choice of which depends on the thickness of the material you want to weld.
For thin and light metals.
This type of pulsed laser is mainly used for welding thin sheets of metal, razor blades, gold jewelry chain links, etc.
Recommended for welding thick parts, it is especially effective on refractory metals. It is more expensive than pulsed laser.
Part 5: How Much Does a Laser Welding Machine Cost?
The handheld laser welder price difference mainly in the hardware brand, configuration and parameters. The handheld laser welding machine is mainly composed of laser welding head, power supply, water cooler, sheet metal cabinet and so on. Of course, the specific price still depends on the quantity and the configuration you need.
Portable Handheld Fiber Laser Welding Machine Cost
Portable handheld fiber laser welding machines range in price from $7,000 to $15,000. Portable handheld laser welding machines are one of the most affordable, it is ideal for small items and precision applications. It’s a great advantage if you can multitask with just one machine, such as 3 in 1 machine for cutting, welding and cleaning purposes. They are easy to use and operate, perfect for beginners.
Robot Laser Welding Machine Price
The laser robot welding machine is a dual-function welding machine, which can realize handheld welding and robot welding. Its price ranges from $18,000 to $40,000. The price of a machine depends on many factors such as brand, model, fiber laser power, and main accessories.
When choosing a fiber laser welding machine manufacturer. Laser welding machine warranty, familiarity with after-sales service response, door-to-door service, life-long technical service, etc. are all factors that need to be considered.
Part 6: Where to Buy the Best Handheld Fiber Laser Welding Machines?
Choosing a handheld laser welding machine may be a difficult task, but there are several factors to consider to ensure you make the best decision. One of the most important factors is the type of materials you will be welding, as different machines are better suited for specific materials.
Different materials and welding methods may have huge differences in the selection of machine configurations. If you have any uncertainties, please feel free to leave a message or contact us, and we will reply you as soon as possible.
