4-Weld Feature Safety
1.Radiation Hazard
Visible and invisible radiation is generated during welding. The interaction
between the high-power laser beam and the target material to be welded can
create a plasma that generates ultraviolet radiation and "blue light," which
can lead to conjunctivitis, photochemical damage to the retina, or a sunburn-
like reaction to the skin. Welders exposed to invisible UV light without proper
protection can suffer permanent eye damage.
2.Skin Hazard
Exposure to infrared and ultraviolet radiation during welding can damage
skin. Infrared and ultraviolet light can cause skin burns, increase welders' risk
of skin cancer and accelerated signs of skin aging. Welding sparks can also
cause burns. Laser material processing can transfer large amounts of energy
into parts. Even after the cutting process is complete, parts can be very hot to
the touch. Make sure to use proper personal protective equipment to prevent
potential burns. Take precautions to prevent skin damage by wearing protective
clothing such as fire-resistant gloves, hats, leather aprons, and other fire-
resistant clothing. Sleeves and collars should be buttoned.
3.Fire Hazard
If flammable or flammable materials are near the welding area, the heat and
