3 Types of Laser Beam Welding and Their Uses

Laser Beam Welding

Laser beam welding is a type of welding that uses a powerful laser to melt and join materials together. It is often used in the automotive, aerospace, medical device manufacturing, and consumer electronics industries. Laser beam welding has several advantages over other types of welding because it can be done quickly and accurately, with minimal heat input into the material being welded and minimal distortion of the material. Let’s take a look at the different types of laser beam welding.

Types of Laser Beam Welding

CO2 Laser Beam Welding

CO2 lasers are the most common type of industrial laser used for laser beam welding. They produce an invisible infrared light that is directed at the workpiece using an optical system or a robotic arm. The infrared light melts the metal molecules together, which creates a strong bond between two pieces of metal or plastic. CO2 lasers are very precise and can be used on thinner materials without overheating them. This makes them ideal for applications where precision is essential such as medical devices or consumer electronics products.

Fiber Laser Beam Welding

Fibre lasers are becoming increasingly popular in industrial settings due to their increased efficiency when compared to CO2 lasers. Fibre lasers use fibre-optic cables to direct their light towards the workpiece, which makes them much more efficient than CO2 lasers since less energy is lost during transmission along the fibre-optic cables. Fibre lasers also have faster scanning speeds than CO2 lasers, making them ideal for high-speed production runs where accuracy and speed are critical factors.

Solid State Laser Beam Welding

Solid-state lasers use solid-state materials such as gallium arsenide or yttrium aluminium garnet to generate their laser beams, making them smaller and more compact than other types of lasers. Solid state lasers also require less power than different types of laser beam welders, which makes them ideal for limited space but still need precise welds quickly, such as automotive manufacturing processes.


Laser beam welding has become an indispensable tool in many industries due to its precision and speed compared to traditional welding forms such as arc welding or TIG welding. Different types of laser beam welders offer other advantages depending on the application they will be used in. So, it’s essential to understand each type before deciding which one best suits your particular needs. With all these options available, one is sure to be perfect for you!
