Handheld laser welding machine is also often called laser welding machine, energy negative feedback laser welding machine, laser welding machine, laser welding machine, laser cold welding machine, laser argon laser welding machine, laser welding equipment, etc. Laser welding uses high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool.

Laser welding machines are mainly aimed at welding thin-walled materials and precision parts. It can realize spot welding, butt welding, stack welding, seal welding, etc. It has a high aspect ratio, small weld width, small heat-affected zone, small deformation, and fast welding speed. The weld is smooth and beautiful, and no treatment is required after welding. It can be precisely controlled, the focused light spot is small, the positioning accuracy is high, and it is easy to realize automation.

So, what issues should we pay attention to when using laser welding machines?

Analysis of matters needing attention in the use of laser welding machine:

Laser, like ordinary light, has biological effects (thermal effect, light effect, pressure effect and electromagnetic field effect). While this biological effect brings benefits to humans, if there is no protection or poor protection, it will also cause damage to eyes, skin and Cause direct or indirect damage to the nervous system and other human tissues. In order to ensure the safety and protection of laser welding machines when working, laser hazards must be strictly controlled and engineering control, personal protection and safety management must be done well.

1. Engineering control of laser welding machine usage precautions

The engineering control of laser welding machine precautions refers to the safety measures taken on the structure of the laser or laser welding machine, mainly including: protective cover - to prevent workers from receiving more than the maximum allowable exposure; safety interlock - Refers to an automatic device connected to the protective cover that can avoid radiation when the protective cover is removed; safety light path - to block the light path that may cause combustion or secondary radiation due to irradiation; key switch - generally refers to the key switch when the key is removed. Laser stalling; beam termination - In order to keep the laser beam within the controlled processing area, a beam terminator or attenuator can be used.

2. Personal protection precautions when using laser welding machine

Personal protection when using laser welding machines mainly refers to wearing fire-resistant and heat-resistant laser protective clothing, laser protective glasses that can selectively attenuate specific laser wavelengths, and laser protective masks for ultraviolet laser sources. . Wear laser protective gloves that can avoid damage caused by direct or scattered laser light.

3. Personal protection and safety management of laser welding machine usage precautions

Personal protection and safety management of laser welding machine precautions mainly include setting up specialized agencies or personnel to clarify responsibilities and rights: including safety training supervision, etc.

The fiber laser welding machine has a high degree of automation and a simple welding process. The non-contact operation method can meet the requirements of cleanliness and environmental protection. Using laser welding machines to process workpieces can improve work efficiency. The finished workpieces have beautiful appearance, small weld seams, large welding depth, and high welding quality, and have a very wide range of applications.
