Welding, Cutting, and Brazing

Health damage due to welding, cutting and brazing operations includes exposure to metal fume and ultraviolet (UV) radiation. The safety hazards of these procedures include burns, eye damage, electric shocks, cuts, toes and finger injuries. Many of these can be managed through appropriate working methods and personal protective equipment (PPE). The following link provides information on the possible dangers associated with these operations and possible solutions.

A: The intensity of light or radiant energy generated during welding, cutting, and brazing work depends on various factors such as light generation, electrode size, arc current and so on. To protect employees who are exposed to strong radiant energy, we start by choosing shadows that are too dark to see welds. Next, reduce the color until you find a hue that allows you to completely observe the weld without falling below the minimum protective hue. A: In order to protect the eyes from the intensity of the specific light generated by the laser, specially designed goggles must be prepared. The level of protection depends on the level of radiation emitted by the laser. If an employee is exposed to a laser beam, the maximum power density or intensity that the laser can generate must be determined. Based on this knowledge, you must choose a lens that interferes with this maximum intensity.
