Choosing the Proper Handheld Laser Welding Machine for Your Application

Portable Laser Welding Machine

Handheld laser welding machines have gained popularity in recent years and are used across numerous industries for their precision, speed, and reduced heat input. However, choosing the right handheld laser welding machine for a specific application can be a daunting task.

What is a laser welding machine?

Laser welding machines, also commonly known as fiber laser welding machines and laser welders, are devices used for laser-based material processing.

Laser welding involves the use of high-energy laser pulses to selectively heat small areas of the material. The intense laser radiation transmits heat through conduction, causing the material to melt and form a specific molten pool, facilitating the welding process.

Hand-held laser welding machines, equipped with portable welding guns instead of fixed optical paths, allow for flexible and convenient welding operations. They offer extended welding distances, overcoming the limitations of workspace and enabling the welding of non-uniformly sized workpieces. These machines are primarily used for welding large workpieces at fixed positions such as internal right angles, external right angles, and flat welding seams. They represent a novel and versatile welding technique for large workpieces, allowing effective welding of carbon steel, stainless steel, galvanized sheet metal, and other metal materials. They are suitable for various welding applications, including sputtering, stack welding, internal and external fillet welding, circular arc welding, and welding of irregular shapes.

How much does a handheld laser welding machine cost?

The cost of handheld laser welding machines in 2023 varies on the market. The Lightweld 1500 laser welding system ranges from $7,850.00 to $9,420.00, while handheld laser welding machines range from $7,850.00 to $13,345.00. The price of air-cooled handheld laser welding machines is around $15,000.00. The variation in prices is primarily due to the configuration of the welding machine.

The cost of a laser welder machine differs based on several factors. These include the thickness of the metal sheet to be welded, the required power of the handheld laser welding machine, the type of nozzle and wire filling system for the laser welding torch, as well as the choice of lasers and water coolers by different handheld fiber laser welding machine suppliers. To find affordable laser welders, it is advisable to thoroughly research welding machine manufacturers.

What are the types of laser welding machines?

Laser welding machines are known by various names, such as laser welding machines, energy negative feedback laser welding machines, fiber laser welding machines, laser cold welding machines, laser argon welding machines, laser welding equipment, and more.

Based on their working methods, laser welding machines can be categorized into manual laser welding equipment (laser mold burners), high-power aluminum laser welding machines, handheld laser welding machines, Lightweld 1500 laser welding system, portable laser welding machines, continuous laser welding machines, vibrating mirror laser welding machines, automatic laser welding machines, jewelry laser welding machines, compound laser welding machines, robot laser welding machines, laser spot welding machines, fiber optic transmission laser welding machines, laser welding and marking machines, and more.

Laser welding machines can also be classified based on the type of laser source they use, such as fiber lasers, CO2 lasers, and YAG lasers. Each of these laser sources has its own advantages and is suitable for different welding materials.

Specialized laser welding equipment includes sensor welding machines, silicon steel sheet laser welding equipment, and keyboard laser welding equipment. Laser welding machines can be used to weld points, lines, circles, squares, or any flat shapes defined by software.
