Compared with traditional argon arc welding, hand-held laser welding has an efficiency improvement of more than 50%. It is smooth and even. It is easy to polish after welding or does not need to be polished. Nowadays, it is widely praised and loved. However, while it is convenient to use a handheld laser welding machine, we should put laser safety in the first place. Below, Leapion Laser shares some precautions for the safe operation of hand-held laser welding machines.
Educate and train the staff operating the hand-held fiber laser welding machine, so that the operator understands the potential risks that may arise when operating the hand-held laser welding equipment, and stop appropriate laser safety exercises for the operator, as well as emergency treatment methods when risks are present.
The management and use of lasers must be terminated by professional (professional) personnel, and those who have not been trained and educated are not allowed to open and use laser machines without authorization. When the machine is delivered to the customer, strict standardized operation training is carried out, and the operation requirements are pasted in a conspicuous place at the operation site. The machine must be operated normally by turning on the host enable switch, holding the gun head power switch, and holding down the light button. , To prevent accidental injury. When the machine is delivered to the customer, it is necessary to strictly carry out standardized operation training, and paste the operation requirements in a conspicuous place at the operation site.
As we all know, the laser of the laser welding machine is a kind of high-intensity light that is excited and emitted. The laser light emitted by the laser source can generally be considered as non-physical when it is inaccessible or invisible; but 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 produced by the cutting for a long time, it is harmful to the eyes and will cause a tingling sensation. The retina is a very sensitive organ, so in the case of long-term viewing of the light source, the operator must wear a radiation protection glasses.
For handheld welding equipment made with fiber lasers, users need full body protection when the power exceeds 1000W. Just watching a scene is not enough, because bare skin will be burned. Therefore, during the operation, the operator should wear protective clothing to protect his safety to the greatest extent.
A large amount of ozone and oxynitride will be produced during laser welding; in particular, the concentration of ozone far exceeds the reference sanitary standard, which has a great impact on human health. Therefore, the work site must have a good ventilation device to exhaust harmful gases and metal dust.
In addition, in addition, fire-fighting equipment must be equipped, such as sand boxes, fire extinguishers, fire hydrants, buckets, etc. The distance of flammable items from the welding place shall not be less than 5m. If the specified distance cannot be met, it can be properly covered with asbestos board, asbestos cloth, etc. to prevent sparks from falling into flammable materials. The distance between explosives and the welding station shall not be less than 10m.
According to laser safety standards, handheld laser welding equipment belongs to the highest safety level of high-power laser equipment. Therefore, when an unknown object enters the optical path, the automatic stop of the laser power is a mandatory function.
At present, many companies are developing new technologies that greatly improve the safety of handheld laser welding equipment. For example, hand-held welding heads with target recognition function, such as hand-held welding heads that can intelligently monitor in real time and warn of faults in time.
