How to use a handheld laser welding machine correctly?

Handheld fiber laser welding machines have become popular in recent years because they not only have all the original advantages of laser welding machines, but also have many advantages such as long-distance operation, flexibility and convenience. Compared with traditional argon arc welding, handheld laser welding has an efficiency increase of more than 50%, smooth and uniform, easy to polish or no polishing after welding, and now it has made its debut in the laser circle. However, while enjoying the convenience of handheld welding equipment, we should put laser safety first! We should strictly follow the regulations when using it. Let's take a look at it together:

1. Knowledge popularization: strict training before taking up the job

Educate and train the staff who operate the handheld laser welding machine so that the operator understands the potential risks that may arise when operating the handheld laser welding equipment, and provide the operator with appropriate laser safety training, as well as emergency treatment methods when risks arise. In addition, the management and use of lasers must be terminated by professional (professional) personnel, and untrained personnel are not allowed to start and use laser machines without authorization. When the machine is delivered to the customer, Fuleis Laser strictly conducts standardized operation training and pastes the operation requirements in a conspicuous place at the operation site. For the machine to operate normally, it is necessary to turn on the host enable switch, hold the gun head power switch, and press the light button to prevent accidental injury. When the machine is delivered to the customer, it is necessary to strictly conduct standardized operation training and paste the operation requirements in a conspicuous place at the operation site.

2. Anti-beam radiation: wear radiation protection glasses and protective clothing

As we all know, the laser of the laser welding machine is a light energy radiation emitted by stimulation. It is a high-intensity light. The laser emitted by the laser source is generally considered to be harmless to the body when it cannot be touched or seen; however, the laser welding machine will cause ionizing radiation and stimulated radiation during the welding process. This induced radiation has a significant impact on the eyes and body. Although the laser beam is very small, the operator generally likes to stare at the beam of the welding machine, but if you look at the sparks generated by cutting for a long time, it is harmful to the eyes and there will be a stinging feeling. The retina is a very sensitive organ, so when looking at the light source for a long time, the operator must wear a pair of radiation protection glasses.

3. Working environment: strictly abide by health standards

A large amount of ozone and oxynitrides will be generated during laser welding; in particular, the concentration of ozone far exceeds the reference health standards, which has a great impact on human health. Therefore, the work site must have good ventilation to discharge harmful gases and metal dust. In addition, fire prevention equipment such as sand boxes, fire extinguishers, fire hydrants, buckets, etc. must be available. Flammable items must be no less than 5m away from the welding site. If the specified distance cannot be met, asbestos boards, asbestos cloths, etc. can be properly covered to prevent sparks from falling into flammable items. Explosive items must be no less than 10m away from the welding site.

4. Equipment selection: quality control is very important

Handheld laser welding equipment belongs to high-power laser equipment with a safety level (IV level). Therefore, when an unidentified object enters the optical path, the automatic stop of the laser power is a mandatory function. The safety of handheld laser welding equipment is greatly improved. For example: a handheld welding head with target recognition function, such as a handheld welding head that can intelligently monitor in real time and timely warn of faults, can reduce potential damage.
