A guide to handheld laser welder safety

The working mode of the handheld optical fiber welding machine.Holding welding in hand is flexible and convenient.
The welding distance is longer. Replace the fixed optical path with a hand-held welding gun.

The handheld fiber laser welding machine mainly used for laser welding of long-distance and large workpieces.
The heat-affected area during welding is small. which will not cause work deformation, blackening, and traces on the back.
The welding depth is large, the welding is firm, and the melting is sufficient. There is no sag phenomenon when the convex
part of the molten material in the molten pool converges with the substrate!

The handheld laser welding machine subverts the working mode of the previous laser welding machine. And replaces the previously
fixed optical path with a handheld welding gun. This mode of operation not only facilitates the welding of products such as molds,
advertisements, kitchen utensils, doors and windows.But also makes it possible to operate laser welding outdoors. This heralds the
replacement of laser welding for the last field of traditional welding such as spot welding and argon arc welding.

Fiber laser welding machine

Compared with traditional argon arc welding, hand-held laser welding improves the efficiency by more than 50%, smooth and even.
It is easy to grind or does not need to  polish after welding.

Now it has debuted at the C position of the laser circle. However, while holding the convenience of handheld welding equipment. we
should put laser safety first. At present, due to the improper use of the operator.There have been many safety accidents: some leaked
light from the welding head burned the leg. Some were laser beam damage to the user’s fundus retina. Some reflected laser light ignited
the surrounding flammable materials and caused a fire, etc.

As a result, the impact will cause users to suffer for life.And manufacturers will also face huge claims. The source of all these accidents reflects
the hidden dangers behind the current explosion of handheld welding equipment.The safety measures of welding equipment are not reasonable
enough, and users have not received good safety training. From a certain perspective, handheld laser welding equipment is like holding a laser
gun.which is extremely dangerous for non-professionals to operate.

 Popularization of Knowledge

When the machine delivered to the customer.It is necessary to strictly carry out standardized operation training, and paste the operation
requirements in a conspicuous place on the operation site. For the machine to operate normally, it is necessary to open the host enable
switch and hand. Hold the gun head power switch, press and hold the light button three switches to prevent accidental accidental injury.

Anti-beam Radiation

Wear radiation protective glasses and protective clothing. As we all know, the laser of the laser welding machine is the light energy radiation
emitted by the excitation and is a kind of high-intensity light. The laser light emitted by the laser source is generally considered to be free of
physical harm when it is not in contact or invisible.But The laser welding machine will cause ionizing radiation and stimulated radiation during

the welding process. This induced radiation will not affect the eyes and the body.

Although the laser beam is very small, the operator generally likes to stare at the beam of the welding machine, but if the sparks produced by
cutting for a long time are harmful to the eyes, there will be a tingling sensation. The retina is a very sensitive organ, so the operator must wear
a pair of radiation protective glasses in the case of long-term exposure to the light source. For hand-held welding equipment made with fiber lasers,
when the power exceeds 1000W, the user needs full body protection. Just one spectacle is not enough, because bare skin will suffer burns.
Therefore, during the operation, the operator should wear protective clothing to protect his safety to the greatest extent.
