Hand-held Laser Welding Machine Advantages

Handheld Laser Welding Machine  advanced instruction

Handheld laser welding machine is one of the fast-rising growth points in the laser field in recent years. It has been recognized by the market with many advantages such as high efficiency, short training time, environmental protection, less consumables, and high scalability

At present, the application field of hand-held laser welding is mainly concentrated in the complex and irregular welding process that does not require fixtures such as sheet metal, chassis, water tank, distribution box and other cabinets, cabinets, kitchen and bathroom, stainless steel door and window guardrails. Compared with traditional argon arc welding and electric welding processes, hand-held laser welding is energy-saving (about 80% to 90% energy saving than argon arc welding), or the welding speed of thin stainless steel plates, iron plates, aluminum plates and other metal materials. , welding quality, and subsequent processing (which can greatly reduce the labor cost of polishing and leveling processes) have obvious advantages, so there is a strong potential to replace traditional processes.

Laser welding is a welding method in which a high-energy laser beam is used as a heat source, and the surface of the material is radiated and heated, and the material is melted and connected by heat conduction. Because laser welding has the advantages of high precision, small heat affected zone, small deformation, and high efficiency , it has a good development prospect. With the continuous development of laser technology and numerical control technology, laser welding has become an advanced processing method in the field of industrial sheet metal welding.

Hand-held laser welding belongs to four types of laser products (greater than 500mW), which is harmful to skin and eyes. However, because workers in many processing factories in China cannot see the existence of the laser, and the sparks during processing are not dazzling, they are carrying out hand-held welding. There are often no safety precautions during operation. This is a very dangerous practice. Although the human eye cannot directly see the laser in the infrared band (the common wavelength of fiber laser is 1064nm), but the welding head of hand-held welding has a certain angle with the surface of the workpiece, and part of the laser will be reflected, especially when welding copper, aluminum and other highly reflective When the material is used, the reflected laser energy is greater, and if it is reflected into the eye, it will cause irreversible damage to the retina. Therefore, we hereby appeal that users of hand-held laser welding must wear laser goggles .
