Although traditional welding machines are safe under normal circumstances, there are still safety risks of radiation and dust during use. While the laser welding machine is a high-energy beam processing equipment, the work of the laser beam energy is highly concentrated, the main role of rapid heating of metal materials to achieve welding. In this process, the laser beam energy will be concentrated in the welding area without causing radiation and pollution to the surrounding environment and personnel.
II. Disadvantages
1. High cost, high maintenance
Handheld laser welding machine as a high-end welding equipment, its purchase cost is high. In addition, the protective lens of the handheld welding gun has a limited service life and needs to be replaced regularly, which increases the cost of use.
2. Limitations
Although handheld laser welding machines are suitable for welding a wide range of materials, there are still limitations in some special cases. For example, for some highly reflective materials (such as copper, galvanized materials, etc.), laser welding is more difficult and requires special treatment or other welding methods. In addition, for some workpieces with a thickness greater than 8mm, the operation of the handheld laser welding machine may be limited.
In recent years, with the significant advantages of high precision, high speed, and small thermal deformation, laser handheld welding is gradually replacing the traditional welding process. Industry data show that in 2024 the global handheld laser welding machine market size has reached about 876 million U.S. dollars, sales of about 160,000 units. In the recently held Essen Welding Exhibition, laser companies launched the handheld welding program, air-cooled program accounted for the mainstream position. Since the world’s first air-cooled handheld welding equipment was introduced in 2021, its market share has soared 300% in just three years.
It is widely recognized that air-cooled solutions have become the optimal choice over water-cooled and refrigerant solutions for power segments below 1,500 W. So, initially positioned as a replacement for the traditional welding process of laser handheld welding, why can get the traditional welding manufacturer’s favor? How can air-cooled handheld welding become a mainstream solution? Next, this article will be combined with the on-site experience of the Essen exhibition, one by one to explore these issues.
Behind the prosperity of handheld laser welding
In this Essen welding exhibition, a number of welding equipment manufacturers focused on displaying a variety of air-cooled handheld laser welding products. With easy operation, excellent weld quality, low cost, green and other outstanding advantages, laser handheld welding can effectively solve the application of many traditional welding scenarios pain points, showing a strong potential for application.
As we all know, the fish scale pattern welding laminated weld due to high sealing, tensile strength and over the flaw detection ability, become the main standard of shipbuilding and other fields. The traditional welding process to form a regular fish scale pattern, the welder’s technical requirements are extremely high, relying on experience and parameters easily lead to inconsistent welds, difficult to meet the high-volume standardized production, and there is a lack of fineness of the problem, the laser welding is therefore the formation of alternative advantages. However, the subsequent emergence of water-cooled laser handheld welding still exists machine bulky, poor portability and other pain points.
In fact, more than 80% of the current market handheld laser welding machine quality issues stemming from the welding gun. The traditional welding gun complex structure, optical path is fragile, bulky and inconvenient to operate, the scope of application is narrowed to argon arc welding, limiting the popularity of handheld laser welding. The welding gun integrates the optical system, gas system and other core components, its lightweight development is facing the “pull one hair and affect the whole body” of the problem, is the key obstacle to promote the lightweight enterprise.
For the above pain points, double pendulum handheld welding HOGI laser in this Essen welding exhibition debut “modular lightweight intelligent” 1600 WHOGI air-cooled fish scale welding handheld welding machine gives the answer.
