Laser welding is a well-known metal joining process that is often used in the automotive industry. It is a type of welding that uses a laser beam to melt and join metals together. The laser beam is focused on the surface of the metal, and the heat from the laser melts the metal. The molten metal is then joined together as it cools. This process is very precise and can be used to weld very small parts.
Laser welding is a popular choice for many applications because it is very precise and can be used to weld very small parts. It is also a very fast process and can be used to weld large quantities of parts in a short amount of time. However, laser welding is not without its challenges. One of the biggest challenges is finding the right laser welding head for the job.
In this article, we will discuss what makes a precision handheld laser welding head ideal for fine work. We will also discuss some of the factors that you need to consider when choosing a laser welding head.
What is a laser welding head?
A laser welding head is a device that is used to focus a laser beam onto a workpiece. The laser beam melts the metal and joins it together. Laser welding heads come in different shapes and sizes, and they are used for different applications. Some laser welding heads are designed for use with handheld lasers, while others are designed for use with stationary lasers.
A laser welding head typically consists of a lens, a mirror, and a beam expander. The lens focuses the laser beam onto the workpiece, and the mirror reflects the laser beam back into the lens. The beam expander enlarges the laser beam so that it can be focused more precisely.
Laser welding heads are used in a variety of industries, including automotive, aerospace, and medical. They are used to weld a variety of materials, including steel, aluminum, and titanium.

Laser welding is a popular choice for many applications because it is very precise and can be used to weld very small parts. It is also a very fast process and can be used to weld large quantities of parts in a short amount of time.
Some of the benefits of using a laser welding head include:
Laser welding is a very precise process. The laser beam can be focused on a very small area, which means that the weld is very clean and there is little to no distortion. This is important for many applications where the weld needs to be very strong and free of defects.
Laser welding is a very fast process. The laser beam can be moved quickly across the workpiece, which means that the weld can be made in a short amount of time. This is important for many applications where time is of the essence.
Laser welding is a very versatile process. The laser beam can be used to weld a variety of materials, including steel, aluminum, and titanium. This is important for many applications where different materials need to be welded together.
Laser welding is a very clean process. The laser beam does not produce any fumes or smoke, which means that the work area is kept clean. This is important for many applications where cleanliness is important.
What are the different types of laser welding heads?
There are several different types of laser welding heads, each with its own advantages and disadvantages. Some of the most common types of laser welding heads include:
Fiber laser welding heads are becoming increasingly popular due to their high efficiency and low cost. These welding heads use a fiber optic cable to deliver the laser beam to the workpiece. The fiber optic cable is very thin, so it can be easily maneuvered around tight spaces. Fiber laser welding heads are also very efficient, converting up to 90% of the laser energy into heat.
CO2 laser welding heads are another popular option, especially for welding thicker materials. These welding heads use a CO2 gas laser to generate the laser beam. CO2 lasers are very powerful, so they can be used to weld thick materials. However, CO2 lasers are not as efficient as fiber lasers, converting only about 30% of the laser energy into heat.
Diode laser welding heads are a newer type of welding head that is becoming more popular. These welding heads use a diode laser to generate the laser beam. Diode lasers are very efficient, converting up to 90% of the laser energy into heat. They are also very compact, so they can be easily integrated into existing manufacturing processes.
Handheld laser welding heads are designed for use with handheld lasers. These welding heads are typically smaller and lighter than other types of welding heads, making them easier to use with a handheld laser. Handheld laser welding heads are also designed to be used in tight spaces, so they are often used in applications where other types of welding heads cannot be used.
What to look for when choosing a laser welding head?
When choosing a laser welding head, there are several factors that you need to consider. Some of the most important factors include:
The type of laser: There are several different types of lasers that can be used for welding, including fiber lasers, CO2 lasers, and diode lasers. Each type of laser has its own advantages and disadvantages, so you will need to choose the one that is best suited for your application.
The size of the weld: The size of the weld will determine the type of laser welding head that you need. For example, if you are welding a large piece of metal, you will need a different type of welding head than if you are welding a small piece of metal.
The material being welded: The type of material being welded will also determine the type of laser welding head that you need. For example, if you are welding aluminum, you will need a different type of welding head than if you are welding steel.
The thickness of the material: The thickness of the material being welded will also determine the type of laser welding head that you need. For example, if you are welding a thick piece of metal, you will need a different type of welding head than if you are welding a thin piece of metal.
The application: The application will also determine the type of laser welding head that you need. For example, if you are welding in a tight space, you will need a different type of welding head than if you are welding in a more open space.
Conclusion
There are several different types of laser welding heads available on the market today. Each type of welding head has its own advantages and disadvantages, so it is important to choose the one that is best suited for your application.
When choosing a laser welding head, you need to consider the type of laser, the size of the weld, the material being welded, the thickness of the material, and the application. By taking all of these factors into account, you can be sure to choose the right laser welding head for your needs.
